references about the fan/radiator model
Hi! I'm looking for references (papers, articles, etc.) about the fan model (a concentrated pressure variation associated with the normal local velocity and some empirical coefficient) in conjunction with the SIPMPLE algorithm on collocated grids. The pressure loss in the radiator model is largely the same think. The fan model is present in the version 4.2 of Fluent as an additional momentum source term associated with some user defined control volumes. This approach is simple but not very realistic because the fan zone is then modeled as a cell zone. The model was strongly improved in version 5.1 (or higher) of Fluent by associating the concentrated / semi-empiric pressure variation with the interface between two cells (edges or faces). The model is more realistic but the numerical treatment must be completely different. Unfortunately there are no reference given in Fluent User's Guide. I must now develop a fan model in an unstructured 2D SIPMLE algorithm and I cannot find any trace of some references. I would be very grateful for any help and piece of information. Thank's in advance!
