Abstract
In this work the network simulation method (NSM) is proposed as a tool for solving the two-dimensional unsteady free convection and mass transfer flow of a viscous dissipative fluid along a semi-infinite vertical plate, taking into account the variation of the viscosity, thermal conductivity, and mass diffusivity with temperature. A spatial discretization, as in finite-difference schemes, is applied to the governing equations, with the time remains as a real continuous variable, and the different analogies (electrical-motion, electrical-thermal, and electrical-mass) developed in this work are applied to solve the problem in an adequate electric simulation program. The effect of variations in viscosity, thermal conductivity, and mass diffusivity with temperature is discussed. The effects of viscous dissipation and the Schmidt number are also studied.
