TURBULENT TRANSITION SIMULATION USING THE k–! MODEL

This paper describes a novel approach in simulating laminar to turbulent transition by using two-equation models. The Total Stresses Limitation (TSL) concept is used to make the two-equation model capable of predicting high-Reynolds-number transitional ow. In order to handle the transition triggered by laminar separation at a low Reynolds number location, which commonly occurs in high speed ow, a sensor is introduced to detect separation and trigger transition in the separated zone. Test cases include the classical at-plate turbulent boundary ow, and low-pressure turbine cascade ows at design and o -design conditions. ? 1998 John Wiley & Sons, Ltd.
