description	This thesis deals with modeling and simulation of an asymmetric plane diffuser which is the most interesting test case in flow field by using Fluent software. The objective of this thesis are to understand the physical of the flow field in the plane diffuser, to evaluate turbulence model performance in predicting flow field using CFD commercial code, FLUENT and to compare with experimental data. The flow behavior includes pressure distribution and velocity profiles in asymmetric plane diffuser was investigated using three turbulence modeling which are realizable k-c model, standard k- co model and SST k- co model. The results from the simulation was compared to the experimental data (Buice & Eaton 1997) in order to produce accurate result.
