“…The experiments to determine the plastic injection molding process are designed using the Taguchi design of experiments by Altan. 19 Eren and Caliskan 20 used Taguchi method to optimize the design parameters of the grooved pin-fin heat exchanger. The authors used bigger is better performance statistics for thermal performance factor and smaller is better performance statistics for friction factor.…”

Space thermal radiators play a significant role in the thermal management of spacecraft. With the increase in heat dissipation requirement, the heat pipe radiators are being replaced by mechanically pumped fluid loop radiators. In recent years, authors proved that optimum serpentine serial radiators are advantageous over conventional optimum parallel radiators in terms of the mass and pressure drop. The spiral radiators, inspired by spiral plate heat exchangers, are proposed and analyzed as a replacement for the serpentine serial radiators. Performance analysis of radiators is carried out using conjugate heat transfer analysis. Conjugate heat transfer results are validated with the experimental results obtained from the literature. The performance analysis indicated that the circular spiral radiator performs better than the other two types due to their lower mass and pressure drop. Optimization of radiators is carried out using Taguchi Signal to Noise ratio analysis. Analysis of Variance is conducted to determine the percentage contribution of each variable to the performance of the radiator. When lower pressure drop requirement is prominent, the contribution of the diameter of the tube is 79.3%, whereas the contribution of fin thickness and pitch of the tubes are only 6.1% and 8.2%, respectively. The contribution of the fin thickness is 57.39%, the diameter of the tube is 37.71%, and the pitch of the tubes is 1.89% when the lower mass of the radiator is the prime requirement. The high-performance spiral radiators may find their application in the thermal management of human space flights and high-power GEO satellites.

“…They worked between the range of Re =1428-3008. Eren and Caliskan [5] experimentally investigated the Nusselt number and friction values using cylindrical pins and triangular pins in a rectangular channel. They prefer air as the fluid and the pins are positioned radially in the channel.…”

In this study, the effects of cylindrical aluminum and Cr-Ni alloy pins placed in different arrangements on the inner wall of the pipe in the turbulent flow, the effects of heat transfer and flow characteristics on different Reynolds numbers have been experimentally investigated. The experiments were carried out under forced flow and constant heat flow conditions. Air is preferred as the fluid and the fluid velocity is adjusted between Reynolds number of 10000 and 50000. It has been observed that the Nusselt values obtained over the number of Reynolds number for the 5 different test tubes are arranged in a line from large to small, sequential row aluminum pin, sequential row Cr-Ni alloy pin, diagonal row aluminum pin, diagonal row Cr-Ni alloy pin, plain tube. There are also CFD analysis for each material, arrangements and pins geometry sets. On the other hand, it was determined that friction coefficient is directly proportional to the increase of heat transfer coefficient. As a result, it is observed that experimental results are compatible with both literature and numerical study.
