Numerical investigation of the three-dimensional development in boundary-layer transition
摘要：
A numerical method for solving the complete Navier-Stoke equations for incompressible flows is introduced which is applicable for investigating 3-dimensional transition phenomena in a spatially growing boundary layer. Results are discussed for a test case with small 3-dimensional disturbances for which detailed comparison to linear stability theory is possible. The validity of our numerical model for investigating nonlinear transition phenomena is demonstrated by realistic spatial simulations of the experiments by Kachanov and Levchenko for a subharmonic resonance breakdown and of the experiments of Klebanoff et al for a fundamental resonance breakdown.
