摘要：

Two-dimensional convective motions driven by uniformly distributed internal heat sources in a fluid-saturated porous medium are analyzed in the large Rayleigh number limit. An integral method is used to obtain a simple analytical representation of the flow field within a rectangular cavity whose vertical side walls are isothermal and whose horizontal boundaries are adiabatic. The results are in excellent agreement with numerical computations based on a finite-difference technique.
