The geometry of the airfoil will affect where the laminar boundary layer transitions into a turbulent one. This can have a major effect on the magnitude of the skin friction drag and, therefore, the performance of the airplane. Boundary-Layer Transition.

EFFECTS OF THE BOUNDARY LAYER TRANSITION ON THE GLOBAL AERODYNAMIC COEFFICIENTS Gustavo L. O. Halila, Alexandre P. Antunes, Ricardo G. da Silva†, João Luiz F. Azevedo† Embraer, Research and Development Branch, São José dos Campos, SP, BrazilFile Size: 1MB.   The ultra-high-lift profile measurements come from a redesign of the BR LP turbine: this is designated the BRUHL LP turbine. This ultra-high-lift profile represents a 12 percent reduction in blade numbers compared to the original BR turbine. The results from NGV2 on all of the turbines show “classical” unsteady boundary layer by:

Review Transition Models for Turbomachinery Boundary Layer Flows: A Review Erik Dick 1,* and Slawomir Kubacki 2 1 Department of Flow, Heat and Combustion Mechanics, Ghent University, St.-Pietersnieuwstr Ghent, Belgium 2 Institute of Aeronautics and Applied Mechanics, Warsaw University of Technology, NowowiejCited by: The Tesla boundary layer turbine is just that. A turbine. And, you use the same equations to solve for its power output that you do for any other kind of turbine. The tricky bit is calculating the energy transfer from the fluid stream to the rotating discs via the boundary layer. (More on that to come). Current models for transition in turbomachinery boundary layer flows are reviewed. The basic physical mechanisms of transition processes and the way these processes are expressed by model ingredients are discussed. The fundamentals of models are described as far as possible, with a common structure of the equations and with emphasis on the similarities between the by:   The analysis is based on the combination of the shear stress transport turbulence model with the transition model, which can handle the laminar boundary layer and its transition to turbulence. The implementation of both models in OpenFOAM is by: 1.
