Selected applications of incompressible viscous flows models

Some of the applications of the Navier-Stokes and consequently also Reynolds-Averaged Navier-Stokes models and their simplifications will be addressed. The range of applications will be divided into three main parts: 1) Atmospheric Boundary Layer flows Several more or less complex test cases have been solved. Starting from wind-tunnel tests and validations the flow complexity increase up to a solution of real-sized problems. Together with the flow solution, the problem of pollution dispersion will be addressed. Examples of computations including some environmental and industrial applications will be discussed. 2) Internal turbulent flows The mathematical and numerical model of 3D curved pipe flow problem will be discussed. Advanced turbulence model will be described together with the details of the finite-volume model implementation. 3) Variable-density and free-surface flows A specific class of the variable-density incompressible flows will be discussed. An example of model computation will be given to show the resolution of water/air interface in the square-sectioned pipe elbow by variable-density approach.
