费托浆态床反应器二维建模讨论? 回复 1# tommy003 数值上的问题有可能是你方程有错误,也有可能就是数值问题。对于这种问题,你可以先把问题简化。比如说 turn off mass transfer between gas and liquid phase, turn off reaction rate. you can simplify the problem to a point where you can solve the problem and can check whether everything is consistent and correct. after that, add the physics back step by step. you may need to use selectors or initialization procedure to aid the initialization. it is somewhat complicated.查看更多
