Insight Into

Conjugate heat transfer has significant relevance to a number of thermal systems and techniques which demand stringent temperature control, such as electronic cooling and chemical vapor deposition. A detailed experimental and numerical study is carried out to investigate conjugate heat transfer in a common configuration consisting of a horizontal channel with a heated section. Experimental data obtained from this study provides physical insight into conjugate heat transfer effects and facilitates validation of numerical conjugate heat transfer models. The basic characteristics of the flow and the associated thermal transport are studied. The numerical model is used to carry out a parametric study of operating conditions and design variables, thus allowing for the characterization of the conjugate heat transfer effects. It is found that the numerically predicted flow field and heat transfer results validate well to experimental observations. Conjugate heat transfer is shown to significantly affect the temperature level and uniformity at the heated section’s surface, channel walls and the gas phase, thus impacting the rate of heat transfer. This study provides guidelines and fundamental insight into temperature control during the combined modes of heat transfer, with implications to various thermal manufacturing methods.

Abstract A detailed experimental and numerical study is carried out to investigate conjugate heat transfer in a horizontal channel with a heated section which simulates Chemical Vapor Deposition (CVD) processing. Since film quality, uniformity and deposition rate have strong dependence on temperature, the role of conjugate heat transfer in influencing temperature distribution is significant in thin film production. Experimental data obtained from this study provides physical insight into conjugate heat transfer effects and allows for comparison and validation of numerical conjugate heat transfer models. The basic characteristics of the flow and the thermal transport are studied. The numerical model is used to perform a parametric study of operational parameters, allowing for the characterization of conjugate heat transfer effects on temperature at the susceptor surface, reactor walls and the gas phase. The study yields valuable guidelines for the thermal design of CVD reactors.
