Abstract

In this paper effects of inclination angle on natural convection flow in an open cavity has been analyzed with Lattice Boltzmann Method (LBM).The angle of inclination varied from θ= -45° to 45° with 15° intervals. Study has been conducted for Rayleigh numbers (Ra) 10 ⁴ to 10 ⁶. The comparisons show that the average Nusselt number increases with growth of Rayleigh number and the average Nusselt number increase as inclination angles increases at Ra=10 ⁴.At Ra=10 ⁵ and Ra=10 ⁶ the average Nusselt number enhance as inclination angels varied from θ= -45° to θ= 0° and decrease as inclination angels increase in θ= 0° to θ= 45°.
