Abstract

This paper presents the numerical simulation of transitional flows. The present simulation uses transition models in the RANS framework, viz. kT -kL-omega model of Walters and Cokljat and gamma−Re_theta model of Menter et al. Both these models are validated for shear flows over flat plate ERCOFTAC test cases. The relative performance of the two transition models for bypass transition flat plate test case (T3A) is discussed. The kT -kL- omega model has been successfully used to simulate SD7003 aerofoil Re = 60000 and prolate spheroid at Re = 40000. and the results obtained are compared with available data.
