摘要：

In this work, the heat transfer performance of circular pin-fin arrays is analyzed by dealing with Reynolds-averaged Navier-Stokes (RANS) equations and compared to the fan-shaped pin-fin arrays. The heat transfer and flow inside a rectangular cooling channel are evaluated using the k-omega and SST turbulence models with the range of Reynolds number of 5000 to 25,000. The result yielded that the heat transfer performance is increased when using fan-shaped pin-fin arrays. The greatest difference is that the fan-shaped pin-fins channel has a smaller Nusselt number at Re = 5000 than the circular pin-fins channel. However, Re = 25,000 changes the least-by 0.11%-of all the values. The friction factor of the fan-shaped pin-fins is lowered greatest at Re = 25,000 as opposed to the 2.04% friction factor of the round design. The fan-shaped pin-fin channel outperforms the circular pin-fin case by 2.9% at Re = 10,000, which is the point at which the heat transfer properties of the two cases differ the most.
