摘要：

In this study we have attempted to compare the heat transfer performance of various commonly used fm geometries. Realistic, manufacturable geometries are optimized for minimizing thermal resistance at moderate laminar air velocities. The basis of comparison was chosen to be a circular array of 1mm diameter pin fins with a 2mm pitch. The pitch-to-width ratio of the other geometries were chosen to provide equal ratios of fin area to base area. CFD simulations were carried out on a two-dimensional computational domain bounded by planes of symmetry parallel to the flow. The air velocity was in the range of 0.5 to 5m/s. A comparison of heat transfer coefficient and pressure drop is presented.
