摘要：

A fluid-saturated porous medium in a rectangular box is heated from below by constant flux. The top is open at constant pressure and the sides are insulated. Linear free convection stability analysis yields a complicated characteristic equation. It is found that the critical Rayleigh number and the incipient mode are sensitive to the dimensions of the box.
