Numerical simulation of transitional flows

The article deals with the numerical simulation of transitional flows. The aim is to evaluate two models for turbomachinery flows. The first model is a simple algebraic model developed by Straka and Příhoda and the second one is the three-equation

Numerical simulation of 2D and 3D compressible flows

The article deals with results of the implementation of the k-kL-ω turbulence model for compressible transitional flow into OpenFOAM. This model was firstly proposed by Walters and Leylek [2] and utilizes the approach of the laminar kinetic energy in order to predict the transition between laminar and turbulent flows. The performance of the implemented model has been tested for the case of flow over a flat plate and the flow through VKI and SE 1050 turbine cascades. The properties of the implementation of the model for compressible flow simulations into OpenFOAM are discussed.
