Abstract
Numerical study of air convection in a rectangular enclosure with two isothermal blocks and oscillating bottom wall temperature was performed under laminar flow condition. The effect of the isothermal blocks on the heat transfer was analyzed for different Rayleigh numbers. The hydrodynamic blockage effect is subdued by the isothermal heating of square blocks. Based on the streamline diagrams, it is found that the formation of vortices is greatly infuenced by the Rayleigh number when all the walls are exposed to a constant wall temperature. The influence of amplitude on the heat transfer is remarkable on the wall exposed to oscillating temperature and is subtle on the opposite static cold wall. The heat transfer increases with an increase in the Rayleigh number and temperature.
