Description	This paper aims to compare numerically the results of 2D flow behavior computed by three CFD codes. The model used to run the programs is an IGV of an axial flow turbine and the data based on the experimental work carried out at the (KTH). The CFD codes used in the computation are in-house two-dimensional codes. H-mesh structure has been used in the computations and k-ε model has been tested for the two turbulent codes. The results indicate that, laminar code predicts clearly the wake behind the vane compared with stage3D, whereas it is limited in turbulent result. The calculations show that at some points just before the trailing edge from 96% to 98% Cax, on the pressure side, the static pressure decreases sharply up to 20 (kPa) for the turbulent and 14 (kPa) for the laminar flow. Also it has been found that the calculated kinetic energy in laminar and k-ε codes are fairly agreed with stage 3D.
