Dormant Capacity Reserve in Lithium-Ion Batteries DetectedTBMG-5214312/01/2024
Lithium iron phosphate is one of the most important materials for batteries in electric cars, stationary energy storage systems, and tools. It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25 percent in practice. To utilize this dormant capacity reserve, it would be crucial to know exactly where and how lithium ions are stored in and released from the battery material during the charging and discharging cycles. Researchers at Graz University of Technology (TU Graz) have now taken a significant step in this direction. Using transmission electron microscopes, they were able to systematically track the lithium ions as they traveled through the battery material, map their arrangement in the crystal lattice of an iron phosphate cathode with unprecedented

OMNI-DIRECTIONAL AUTONOMOUS GUIDED VEHICLE (AGV) WITH WIRELESS NAVIGATION2024-01-343611/15/2024
ABSTRACT Automatic guided vehicles (AGV) have made big inroads in the automation of assembly plants and warehouse operations. There are thousands of AGV units in operation at OEM supplier and service facilities worldwide in virtually every major manufacturing and distribution sector. Although today’s AGV systems can be reconfigured and adapted to meet changes in operation and need, their adaptability is often limited because of inadequacies in current systems. This paper describes a wireless navigated (WN) omni-directional (OD) autonomous guided vehicle (AGV) that incorporates three technical innovations that address the shortfalls. The AGV features consist of: 1) A newly developed integrated wireless navigation technology to allow rapid rerouting of navigation pathways; 2) Omnidirectional wheels to move independently in different directions; 3) Modular space frame construction to conveniently resize and reshape the AGV platform. It includes an overview of the AGVs technical features

Design of Hybrid Air Conditioning System Using Phase Change Material for Commercial Sleeper Vehicles2022-28-044811/09/2022
Many road accident happens due to fatigue & deprive sleep of drivers. Many times driver use AC system for their quick thermal comfort during night with engine ON. This scenario is very critical from human's safety & vehicle functionality point of view. This also consumes additional 10-15% of fuel requirements in AC running condition. So, to address social problems of driver's sleep & pollution free environment by reducing the use of fossil there is a need of alternative techniques for air cooling which works during engine OFF condition. Various alternatives options for air cooling have been reviewed & extensive evaluations are mapped on the various performance parameters. Based on this the phase change material technology can be easily adopted due to its packaging flexibility. Phase change material (PCM) technology available in the market since decades for the use of storing the thermal energy.

Faster Cool-Down of a Reefer Unit by Optimizing the System Losses through Experimental Investigation2022-28-044211/09/2022
Refrigerated shipping containers are one of the four segments of the cold chain; cooling and storage; refrigerated transport; distribution centre and refrigerated display in super markets. The term reefer has become an established term to refer refrigerated shipping containers. It is one of the emerging areas in transport segments. With the onset of ongoing pandemic this area has further drawn global attention recently and due focus is being given to the development and improvement of reefer unit Hence with the growing demand in this field the energy consumption is also leapfrogging day by day. Primary energy sources (fossil fuel) are depleting and their environmental impact is raising anxiety around the world. In order to minimize unnecessary energy waste in refrigerated shipping container system, it needs to be designed to be energy efficient and provide high cooling capacity to ensure rapid pull down to carriage temperature and to maintain product quality at idle.

Murraya koenigii based nano-drone deployment for Titan exploration2022-26-119405/26/2022
Titan is currently been dubbed as a potential home to humanity, owing to its atmosphere and earthlike liquid cycle. Hence, it is important to make a vast study to understand the nature of the largest moon of Saturn. This paper proposes a cluster-based nano-drone deployment. With the main recharging parent drone-flight in between that clutches onto the daughter nano-drones in an opposite-arrangement, these kind of drones can be used for long-range autonomous surveillance purposes. When the entire-flight arrangement system enters the radius of surveillance, the drones detach themselves with a mechanism copied from the plant Murraya Koenigii, using pneumatic technologies. Once they are deployed and their periods are complete, they get back to the parent drone for recharging and relocation purposes. The drones can also be controlled remotely from the earth. The central stem has massive power storage capacity and VTOL capabilities, giving it high maneuverability and control. The recapturing

Pseudo Transient Torque Converter Clutch Engagement Process Using Fluid-Structure Interaction Simulation2022-01-078103/29/2022
This investigation utilizes a correlated fluid-structure interaction (FSI) model of the torque converter and clutch assembly to perform a pseudo transient clutch engagement at steady state operating conditions. The pseudo transient condition consists of a series of nine steady state simulations that transition the torque converter clutch from fully released to near full lockup at a constant input torque and output speed representative of a highway cruising speed. The flow and pressured field of the torque converter torus and clutch are solved using a CFD model and then passed along to a transient structural model to determine the torque capacity of the lockup clutch. Bulk property assumptions regarding the friction material, deformation of the clutch plate and deflection of supporting structures were made to simplify the model setup, run time and solution convergence. Telemetry pressure measurements acquired in an operating torque converter under similar operating conditions on a

OSC modelling of 3-way automotive catalysts to understand the effect of latent OSC on dynamic OSC performance2022-01-069303/29/2022
A Three-way automotive catalyst's ability to store oxygen is still a crucial performance metric for modern day catalyst applications. With more stringent emissions legalisation, the oxygen storage capacity (OSC) within the catalyst can assist with converting different exhaust gases such as CO, THC and NOx under transient operating conditions. OSC is currently the only onboard catalyst performance metric recorded during a vehicle's useful life. Catalyst performance is correlated to this OSC measurement. OSC in 3-way automotive catalysts can be split into two main OSC types. "Latent OSC" deep within the layers of the washcoat and "dynamic" OSC on the surface layers of the catalyst washcoat. Dynamic OSC is more commonly applied in the evaluation of the activity of the catalyst during practical operation. This paper uses a kinetic OSC model with a layered washcoat approach to analyse OSC test data and show how latent OSC can affect the dynamic OSC performance of a 3-way catalyst. Model

Ducted Fuel Injection: An Experimental Study on Optimal Duct Size2022-01-054303/29/2022
Ducted fuel injection (DFI) was implemented in a constant flow High Temperature Pressure Vessel (HTPV) at 60bar ambient pressure, 800-1000K ambient temperature, 21% oxygen. The ducts were 14mm long and placed approximately 3mm away from the orifice exit. The duct diameters ranged from 1.6-3.2mm and had a rounded inlet and a tapered outlet. Diesel fuel was used in a single-orifice fuel injector operating at a rail pressure of 250MPa, where the orifice diameters ranged from 150-219µm. The objective of this work was to study soot reduction for various combinations of orifice diameter in relation to duct diameter. Several combinations of orifice and duct diameters were tested. A complete data set was taken using the 150µm orifice. The results clearly show that soot reduction peaks at an optimal duct size of 2-2.25mm and is reduced as the duct diameter is increased or decreased. A smaller number of test points were also taken using the 169 and 219µm orifices, showing similar trends

Development of a transmission-illumination-based crack detection method using translucent tools for testing of thin-walled metal sheets and foils2022-01-027503/29/2022
The formability of thin-walled metallic sheets and foils is increasingly gaining in importance in the automotive industry and in medical and food packaging. As a result, the demand for methods to test the deep drawing and stretch forming capabilities of these materials is increasing significantly as well. In deep drawing and stretch forming, the in-situ crack detection is either performed manually by purely visual evaluation by the machine operator or automatically by a crack detection system. The automatic crack detection method commonly integrated in sheet metal testing machines functions by analyzing the drawing force during forming. However, friction, vibration, and machine noise are disturbance variables that prevent crack detection in thin sheets and foils. The same disturbance variables also prevent robust crack detection in thin sheets and foils by systems that analyze structure-borne sound. Crack detection systems that use reflected light methods, on the other hand

“One-Way” Electronic DevicesTBMG-3779910/01/2020
Waves — whether they are light waves, sound waves, or any other kind — travel in the same manner in forward and reverse directions. This is known as the principle of reciprocity. If waves could be routed in one direction only — breaking reciprocity — many applications could be transformed by enabling “one-way” components such as circulators and isolators that enable two-way communication, which could double the data capacity of today's wireless networks. These components are essential to quantum computers that read a qubit without disturbing it. They are also critical to radar systems in self-driving cars or those used by the military.
