N2 - A finite difference two-dimensional unsteady elliptic (the influences from downstream locations can extend to upstream ones) computer program is used to calculate the concentration gradient required to stabilize the temperature gradient in salt-gradient solar ponds with heat removal and bottom and side wall heat losses. Available stability criteria are reviewed. The criterion developed by Weinberger and Tabor is modified to obtain the temperature gradients. The computational domain, which consists of the pond, ground, and side wall, was divided into two regions. The first, which consists of the pond and the ground beneath the pond, was modeled as an unsteady one-dimensional region. The second, which consists of the side wall and the ground beneath the side wall, was treated as an unsteady two-dimensional region. The effect of the pond dimensions and the heat withdrawal on the concentration gradient which is required to stabilize the pond is presented. The concentration gradient required to stabilize the pond at different times during the heatup period is also presented.
