摘要：

A porous structure with partial heating and evaporation on the upper surface is studied analytically. The liquid pressure and velocities are obtained by solving a Laplace-type equation for the porous structure. A perturbation method is applied for the temperature distribution with higher heat inputs, which consists of zeroth-order solution and a temperature correction. For the temperature correction, an approximate solution is derived using an integral formulation. The analytical solution obtained is useful for the evaporator performance and design of capillary pumped loops.
