Introduction to the mathematical modelling of turbulent compressible fluid flow
of turbulent compressible fluid flow. The paper briefly reviews the conservative system of the Navier-Stokes equations for laminar compressible flows. The Reynolds and Favre mass-averaging procedure is introduced....

CFD study of flow similarities in turbulent regime in a stirred tank
The CFD simulations of flow in a stirred tank in fully turbulent regime were investigated. The flow Reynolds number was changed in two ways: change of impeller speed and using different values of kinematic viscosity. Result...

Unsteady turbulent flow with adverse pressure gradient.
Velocity and wall shear stress measurements in a periodic turbulent flow with adverse pressure gradient were performed in a conical difuser (air flow) and in a water diverging channel, both with the total divergence angle 6...

Model of averaged turbulent flow around cylindrical column for simulation of the saltation
in vicinity of a high cylindrical column. It is assumed that an averaged turbulent flow is horizontally layered in vicinity of the cylinder. In each layer the flow around the cylinderis modelled as a potential

Performance of several turbulence models in impinging jet flows.
Turbulent impinging jet flow was numerically modelled using Reynolds averaged Navier-Stokes equations with several one- and two-equation linear and non-linear low-Re turbulence models. The SST model proposed by Men...
