ABSTRACT

This study uses an inverse method and commercial package FLUENT along with the experimental data to obtain heat transfer and fluid flow characteristics of plate-fin heat sinks placed in a rectangular enclosure with two openings. A cooling fan placed on the top of the fins is blown downward. Another fan is placed on the outside of the opening in order to extract the air inside the enclosure. The inverse method along with the experimental temperature data is applied to estimate the heat transfer coefficient on the fins. Afterward, a commercial package FLUENT along with the zero-equation turbulence model, experimental temperature data and the resulting heat transfer coefficient is used to obtain heat transfer and fluid flow characteristics of plate-fin heat sinks within a rectangular enclosure with openings. The resulting heat transfer coefficient and fin temperature at the selected measurement locations are close to inverse results and the experimental temperature data, respectively. Thus, the zero-equation turbulence model is suitable for this problem.
