خلاصه مقاله:
Some of the typical turbulence models were tested for Tehran refinery cat alytic reforming unit in order to find t he best model. Experim ent al dat a of pressure drop through the react ors was used for accuracy m easurem ent of applied models and somehow for validat ion of CFD results. Several runswith different turbulence models were established upon a unique geometry of the working system. Effects of additional import ant factors like wall roughness, w all functions, Y-plus on the flow field and t otal pressure drop were st udied as well. Am ong turbulence m odels test ed, it is found that theRSM model may be the best crude model to predict tot al pressure drop. Considering wall roughness, we found t hat the well-known standard k-ε model is also capable of estim ating pressure drop wit h acceptable confidence bound.
