內容摘要：
An optimization of heat transfer design problem is presented in the realm of convective boiling phenomena. In the world of heat transfer design problems it now quite well-known that CHF (Critical Heat Flux) is the most efficient and critical heat transfer condition that designers seek. This study shows a method of predicting CHF (Critical Heat Flux) in vertical round tubes that have both uniform and cosine or non-uniform heat flux distributions. Initially a uniform correlation, based on local condition hypothesis, was developed from 9,366 CHF data points of uniform heat flux of water flowing in vertical upward tubes. The CHF database collected from 13 different sources had the following wide parameter ranges: 1.01主講人介紹：
