Numerical solution of viscous flows

Project goals

The project deals with numerical solution of 3D viscous and (partly) inviscid flows: a) 2D and 3D transonic flows through a cascade or over a profile (a wing) based on inviscid model (Euler equations) of transonic flows or viscous (laminar) model of Navier-Stokes equations; b) 2D and 3D impinging (or free) turbulent jet flows based on a system of Reynolds averaged incompressible Navier-Stokes equations and turbulence modelling (algebraic, k-L, k -e) model; c) 3D atmospheric boundary layer flows: based on incompressible Reynolds averaged Navier-Stokes equations. We consider turbulent flows with behavior of pallotants and computation field of temperature. Numerical part is based on finite volume methods (a,b) or finite difference method (c) and modern TVD,ENO or semiimplicit or implicit schemes.

    Numerické řešení vazkého proudění

  • Annotation in Czech

    Úkolem je vývoj numerických metod pro 3D transonické obtékání mříže, 3D vazké turbulentní proudění kolem povrchu země (kopečku či systému kopečků) a 3D turbulentní proudění proti stěně. Proudění kolem země (kopečku) uvažuje i šíření škodlivin v ovzduší
