Abstract This work presents a simulation of the phenomena of natural convection in an enclosure with a variable heating
regime by the lattice Boltzmann method (LBM). We consider a square enclosure of side H filled with air (Pr =
0.71) and heated from below, with a hot portion of length L = 0.8 H, by imposing a sinusoidal temperature. The
unheated segments of the bottom wall are treated as adiabatic, and one of the vertical walls features a cold region,
while the remaining walls remain adiabatic. The outcomes of the two-dimensional (2D) problem are depicted
