Effect of Variable Thermal Conductivity on Buoyant Convection in a Cavity with Internal Heat Generation

Effect of Variable Thermal Conductivity on Buoyant Convection in a Cavity with Internal Heat Generation

A numerical study has been made to analyze the effects of variable thermal conductivity on the natural convection of heat generating fluids contained in a square cavity with isothermal walls and the top and bottom perfectly insulated surfaces. The flow is assumed to be two-dimensional. Calculations...
