A numerical simulation of natural convection was conducted in the middle of a rectangular cavity with a heater of variable dimension.Analyses on isotherms
streamlines and average Nusselt number in the rectangular cavity were carried out by varying the values of dimensionless height b and Rayleigh number.The simulation results show that b and Ra have a great effect on the natural convection in the rectangular cavity.Nuave grows with the increase of b and Ra
and the growth rate is proportional to Ra and inversely proportional to b.
