Numerical calculations for the two dimensional reattachment jet flow fields having offset ratio 2.5 were done by skew upwind scheme method and compared with experiments. The standard and modified k-ε models are used as turbulence models and the modified one is considered the streamline curvature effect and preferential dissipation. In experiments, the nozzle exit velocity is 30m/s and the turbulent intensity is 0.2% at the nozzle exit. The reattachment length in the calculated results by the modified k-ε model has 3% error with the experiment. And the modified k-εmodel is better than the standard one for prediction the mean velocity field and static pressure field in this case.
