Abstract
RANS models assume that the flow is completely turbulent and in some flows the laminar region is so small that it becomes a valid consideration. However, in some specific cases the laminar region may correspond to up to 30% of the flow, as in airfoils. To identify this laminar region and the transition process, have been developed transition models that interact with the RANS turbulence models. In this work the transition model SST-Gamma-Theta is used to identify the laminar-turbulent transition process on a flat plate and the results are compared with those obtained experimentally in the ERCOFTAC T3AM test, as well as those obtained using the RANS SST common model.
