Description
  • This paper deals with the numerical solution of the turbulent flow over a built-up area. Currently, our model consists of one simple house in two dimensions. The mathematical model is described by the RANS (Reynolds Averaged Navier Stokes) system of equations. The numerical approximation is based on the FVM (Finite Volume Method) with the AUSM (Advection Upstream Splitting Method) scheme and the PLR (Piecewise Linear Reconstruction) limited by the Barth-Jespersen limiter. The turbulence was modelled by k-omega TNT two-equation turbulence model. Our numerical result was compared with the experiment carried out by ARTI in their BLWT (Boundary Layer Wind Tunel).

  • V tomto článku se zabýváme numerickou simulací turbulentního proudění zastavěnou oblastí. V současné době námi řešený případ je tvořen jedním domem modelovaným ve 2D. Použitý matematický model jsou Reynoldsovy středované Navierovy-Stokesovy rovnice doplněné k-omega TNT turbulentním modelem. Numerická aproximace je založena na metodě konečných objemů, kde numerické toky byly počítány AUSM (Advection Upstream Splitting Method) schématem. Pro zvýšení řádu přesnosti v prostoru byla použita po částech lineární rekonstrukce s Barth-Jespersennovým limiterem. Výsledek je porovnán s experimentem, provedeným ve VZLU v tunelu pro mezní vrstvu. (cs)
