Popis:	A vertical two-dimensional model of mixed (free and forced) convection is developed for a geothermal system in which permeability varies continuously.A formula for two-dimensional flow is derived for computing interblock permeabilities which varies more or less linearly between centers of finite difference blocks.Using the above formula in the vertical two-dimensional model of mixed convection, the temperature and pressure distributions are estimated for cases where the variation in permeability is linear between centers of finite difference blocks.Eventually, this model is applied to the Okuaizu geothermal field in Fukushima prefecture. Then, flow and temperature fields in the entire system consisting of fractured zones and impermeable zones are obtained.
