### LATTICE BOLTZMANN SIMULATION OF TURBULENT NATURAL CONVECTION IN TALL ENCLOSURES

**ABSTRACT**

In this paper Lattice Boltzmann simulation of turbulent natural convection with large-eddy simulations (LES) in tall enclosures which is filled by air with Pr=0.71 has been studied. Calculations were performed for high Rayleigh numbers (Ra=107-109) and aspect ratios change between 0.5 to 2 (0.5 Keywords: lattice Boltzmann method, large eddy simulation, aspect ratio, natural convection
