| Резюме: | Заглавие с экрана The objective of this study is to compare the three models used for describing the flow of fluid inside porous fins attached to the heated wall of a differentially-heated square cavity: Darcy, Brinkman and Brinkman-Forchheimer models. A wide range of Rayleigh and Darcy numbers were investigated while the fin length, position and relative thermal coefficient were kept constant. Finite-difference method was used for solving governing equations. It was found that the Brinkman and Brinkman-Forchheimer models yield almost the same results at any Darcy numbers while the Darcy model is unstable at high Darcy numbers. Текстовый файл |
