Investigation of the geometrical effect of two solid partitions on the natural convection in a square cavity

This work aims to examine the impact of two horizontal solid partitions placed on the vertical walls of a differentially heated square cavity. The vertical sides are at different temperatures, while the horizontal sides are adiabatic. The obtained result show that the two solid partitions trap some...

description	This work aims to examine the impact of two horizontal solid partitions placed on the vertical walls of a differentially heated square cavity. The vertical sides are at different temperatures, while the horizontal sides are adiabatic. The obtained result show that the two solid partitions trap some fluid in the cavity and affect the flow fields. Furthermore, the Nusselt number increases as the Rayleigh number increases and decreases with the length of the partition for the high Rayleigh number. Nevertheless, the length impacts positively in the low Rayleigh number. Finally, we can see that the Nusselt number changes negatively or positively if the position of the partitions accelerates or trap the fluid motion.
