Entropy Generation Analysis in Convective-radiative Cooling Composite Walls with Temperature-dependent Thermal Conductivity and Internal Heat Generation

摘要: Abstract This work analyses entropy generation in composite walls which lose heat with both convection and radiation, simultaneously. Temperature-dependent thermal conductivities internal generations are assumed for materials. The nonlinear system of differential equations is solved the transformation method (DTM) a semi-analytical technique. temperature data derived from DTM validated against analytical solution convective temperature-independent generations. In view fact that one classical examples many scientific communities, local total presented this study can be useful addition engineering fields where wants to minimize irreversibility system.
