WebbIf Thwaites method is being used, λ and H are of course uniquely related, so in that case the change would be trivial. With the two-equation BL formulation used in MISES, however, they are not uniquely related, with H lagging λ somewhat. Using H instead of λ to parameterize boundary layer instability growth is theoretically more sound, since the Webb18 juli 2011 · 9.6 Thwaites’ Method. 9.7 Transition, Pressure Gradients, and Boundary-Layer Separation. 9.8 Flow Past a Circular Cylinder. 9.9 Flow Past a Sphere and the Dynamics of Sports Balls. 9.10 Two-Dimensional Jets. 9.11 Secondary Flows.
