Modelling of the wall roughness effect on the boundary layer transition using the algebraic transition model
Original language description
The contribution deals with the numerical simulation of the wall roughness effect on the laminar/turbulent transition using the algebraic transition model. The existing relation for the transition onset including the effect of pressure gradient and free-stream turbulence was extended by means of available empirical correlations for the wall roughness effect. The algebraic model of the bypass transition used in conjunction with the EARSM turbulence model was verified using incompressible flow on the plate and used to calculate the compressible flow through a turbine blade cascade with rough blades. Performed calculations show an acceptable agreement with the experimental results.
