С. 19-21Abstract: Numerical analysis of natural convection inside a partially porous cavity filled with a fluid of variable viscosity is carried out in the presence of a heat-conducting energy source. It is assumed that the liquid temperature is not equal to the temperature of the porous matrix, therefore the local thermal non-equilibrium model (LTNE) is used for modeling. Governing equations formulated in the dimensionless stream function, vorticity and temperature were solved by the finite difference method. The obtained results showed an opportunity to improve the passive cooling system using the porous insertions.
