Regarding a suitable scheme for BFC

Abhijeet Vaidya

Hello, I want to develope a 3-d code which will be a flow solver with turbulence and spray models and based on the transformed equations ( solver for a body fitted grid ). Since in finite volume method, there are a huge number of schemes, I am feeling confused because each has its own advantages & disadvantages. Out of all algorithms, I have decide that I will use either K.C.Karki's (1988, karki & patankar, NHT publication ) scheme, based on staggered grid or S.Mujumdar's scheme, which is based on non staggered scheme of Rhie and Chow ! Though the non staggered scheme approach looks simpler, I am not feeling confident whether it will really be stable or will it give problems regarding convergence ( specifically as I have to solve spray also). Kindly guide me for this ! Thanking you !
