AB In the present study, for the first time, LES of the D3Q19 Fractional Volumetric Multi-Relaxation-Time Lattice Boltzmann
(FV-MRT-LB) model in conjunction with both Smagorinsky and mixed scale viscosity subgrid closure models is applied to
a three-dimensional turbulent natural convection flow in a side-heated cubic cavity at different Rayleigh numbers up to 10<sup>12</sup> for a Prantdl number of 0.71. The results show that the (Hybrid Thermal) HT-FV-MRT-LB LES method produce reasonably accurate results at low Rayleigh numbers and stable results at high Rayleigh numbers.
