Development and analysis of heat exchanger for efficient heat transfer for L-shape wind tunnel

Abstract

As automation and mechanical industry growing towards next era, it becoming crucial to design each element of plant with more productive material. Out of many parameters, heat transfer is very important area of study to lower the rate of failure of numerous machines. For heat transfer control there is a need of design of efficient heat exchanger. A heat exchanger can be designed for minimization of heat energy from the wind tunnel. Impact on HE performance is important due to the thermal resistance of wind tunnel. Thermal resistance is the heat property of the tunnel material and dimensions of tunnel. Looking at application level performance, the thermal resistance is crucial element in case of aerodynamic study. The similar study is done for Apolo11 spacecraft which was important in case of landing back to earth as traveling to earth with high speed generated heat which can damage spacecraft body. Such study further leads to various domains like material research, human impact study etc. The most recently, asteroid is passed nearby of earth orbit, where aerodynamic study of NASA evaluated the pre-collision effects where thermal properties are analyzed considering the atmospheric nearby orbit as a tunnel of wind/pressure. Hence, the scenarios must be considered for heat transfer / heat exchanger design specific to the each application domain. This paper discusses about the asteroid bypass which generates heat as a major heat transfer to earth and the automobile specific modeling of heat exchanger for wind tunnel. The focus is kept on heat exchanger design which can be suggested for automobile testing procedure.
