Implementation of an Optimization Method for Inverse Heat Conduction and Sensor Position Correction

R. Dalshad1, N. Perakis2, M. Pfitzner1, O. J. Haidn2
1Institute for Thermodynamics, Bundeswehr University Munich, 85577 Neubiberg, Germany
2Chair of Turbomachinery and Flight Propulsion, Technical University of Munich, 85748 Garching, Germany

Heat conduction problems can be divided into direct and inverse problems. In direct problems, the thermal boundary condition (heat flux or temperature) is given and its effect is calculated, while for inverse problems the boundary condition is determined based on its effect. For some ... Read More

A hybrid energy harvesting based on lead free piezoelectric materials at constant temperature

Neetu Kumari1, Micky RAKOTONDRABE 2

As additive manufacturing for metallic material is more and more used in industry, researchers try to overcome the limits of the process. To improve this industrial process, in terms of applications and understanding, the numerical simulation is today a very strong tool. Nevertheless, ... Read More

Design optimization of a battery rack system based in thermal analysis

Hamza Saiger1, Ishant Jain1
1Raychem Innovation Center, Vadodara, India

Verification for thermal performance of battery stack system is of critical importance during the design stage of any energy management system. The temperature of batteries during charging and discharging cycles should not exceed a permissible value. In current analysis work, ... Read More

Twin Side HTLS connector with high heat dissipation power for 1500 amp current pass

Abhijnan Chowdhuri1, Raghav Upasani1, Ishant Jain1
1Raychem Innovation Center, Vadodara, India

In modern days one of the biggest challenges is to have a special connector for very high current power supply which shouldn’t exceed the rating temperature of 90°C at full load. This main challenge it to design special connectors of aluminum (Al). In this study, a new approach is ... Read More

Sara Liparoti1, Vito Speranza1, Francesco Marra1
1University of Salerne, Dept of Industrial Engineering, Italy

Injection molding is one of the most diffused processes for mass production of polymeric components. It is adopted in many fields, from the automotive one to the biomedical field. The aspects related to environmental pollution make mandatory the reduction of plastic wastes, especially ... Read More

Thermal study of wafer cooling and heat resistance fitting

Hervé ROUCH1, Fabrice BOILOT1
1INOPRO IAO, Villard De Lans, France

Temperature management and homogeneity on wafers has always an important effect on production in all microelectronics fields. The heat resistance of every mechanical contact, not only clamping, may decrease the precision of temperature regulation. But they also increase the difficulties ... Read More
