Abstract:V magistrski nalogi je opisan pristop k reševanju naravne konvekcije pri visokih Rayleighjevih številih. Z metodo končnih volumnov smo izvedli URANS- in LES-simulacijo. Za URANS-simulacijo je bil uporabljen SST-turbulentni model, za LES-simulacijo pa smo uporabili dinamični Smagorinsky-Lillyjev model. Ker je za izvedbo LES-simulacije potrebna velika računalniška moč, smo tridimenzionalno domeno poenostavili v dvodimenzionalno. Končni rezultati so se med sabo dobro ujemali. Med tridimenzionalno in dvodimenzionalno obravnavo so se pokazale nekatere razlike.

Title:Numerical simulation of the turbulent Rayleigh-Benard natural convection
Abstract:The content includes two ways how to solve a natural convection problem at very high Rayleigh numbers. With the fine volume method, we performed a URANS and LES numerical simulation. For the URANS simulation, we have used the SST turbulent model and for the LES simulation, we have used the Dynamic Smagorinsky-Lilly model. To perform the LES simulation the needed computer power was very high. We had to change the three dimensional domain into two dimensions. The results shown a good agreement. There were some differences between the three and two dimensional, domain.
Keywords:Rayleigh-Bénard natural convection, natural convection, turbulent natural convection, natural convection between two horizontal walls, computational fluid dynamics, dynamic of turbulent flows, numerical simulation of turbulent Rayleigh- Bénard natural convection, fine volume method, non-stationary simulation
