“…In addition, long-term use of the refrigerator will lead to ash accumulation, increase the air side pressure drop, and reduce the working performance of the refrigerator. ZHANG [4] et al took dust composition, dust volume and scaling speed as factors affecting air side scaling, tested the performance changes of exchanger with different structure sizes in household refrigerators before and after scaling, and observed and analyzed the formation of scaling.…”

“…Mathematical evaluation is an effective application which usually utilized for distinctive research and several areas [9,10]. The moment working with the heat transfer of compressed heat exchangers, it provides probability to check and replicate a variety of diverse models within several functioning circumstances with no requirement of designing of extremely costly actual proportions representative models [11,12]. However, mathematical designs with no evidence of abilities can be deceptive [13,14].…”

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.

“…The effect of fouling have been experimentally studied in the laboratory environment with various different standard dust types by various authors. An experimental study by Zhang et al [31] for air conditioning application, con-cluded that interrupted louvre fin shapes are more prone to fouling in a microchannel design than a planar fin. One of their main conclusions was that the interior of the heat exchanger with louvre fin is more vulnerable to fouling, whereas with the plain fin, the fouling occurs in the front surfaces.…”

“…They emphasized that the type of the fin plays a prominent role in the fouling characteristics of the heat exchanger. [31] The microchannel heat exchanger and dry coolers were studied by Bell et al [32,33], who concluded an increase of up to 50% due to fouling on the pressure drop on the air side. Zhan et al [34] studied the wavy fin-and-tube heat exchanger and concluded that areas that are most prone to fouling are the leading edge of the fins and the front part of the tubes.…”
