| description | Mathematical simulation on unsteady natural convection in a closed porous cylindrical cavity having finite thickness heat-conducting solid walls in conditions of convective heat exchange with an environment has been carried out. A boundary-value problem of mathematical physics formulated in dimensionless variables such as stream function and temperature on the basis of Darcy-Boussinesq model has been solved by finite difference method. Effect of a porous medium permeability, ratio between a solid wall thickness and the inner radius of a cylinder, a thermal conductivity ratio and a dimensionless time on both local distributions of isolines and isotherms and integral complexes reflecting an intensity of convective flow and heat transfer has been analyzed in detail. |
