摘要

By using an optimal method coupled with the numerical simulation of the response surface methodology and genetic algorithm, the geometric configuration for two-dimensional ribbed channels is optimized in this paper. The parameters studied are the height of rib, the thickness of rib, and the pitch. The objective of optimization is to maximize the performance factor of the ribbed channel. The results show that the optimal method works for an optimized design of a two-dimensional ribbed channels. The ribs are demonstrated such that they can significantly affect the heat transfer rate and the friction factor. For the in-line ribbed channel, the performance factor increased by 1.1-1.5. In a staggered ribbed channel, the performance factor reached 2.681.
