On the development of methods of the laminar-turbulent transition prediction

The problem of calibration of semi-empirical eN-method for prediction of laminar-turbulent transition in three-dimensional boundary layers is discussed. A high-resolving panoramic experimental technique to estimate the onset and length of the transition for aerodynamic applications is proposed and described. The position of laminar-turbulent transition is estimated also using the developed techniques for computing three-dimensional laminar-turbulent flow at a swept wing using an original transition module developed on the basis of the author’s software bundle LOTRAN 3, the module being integrated into ANSYS Fluent.
