Heat transfer of nano powder inside a porous tank with use of non-equilibrium approach

In current numerical investigation, irreversibility and energy transportation related to free convection though a porous wavy chamber was scrutinized. One of the essential factors in design of unit is irreversibility which should be minimized. The inner wavy surface acts as heat element and chamber is filled with hybrid nanomaterial. New correlations, contours and profiles are main kinds of outputs which achieved by employing CVFEM. As Ra augments, the magnitude of psi(max) enhances which indicates higher convective mode, and better cooling rate of inner wall happens. At lowest Ra and Nhs, Nu declines about 57.2% and Be augments about 2.75% with augmenting Lorentz force. Nu becomes 7.5 times greater with growth of Ra when other variables are minimum. Be reduces about 2.49% with rise of Nhs at Ra* = 5, Ha = 20. Portion of thermal irreversibility augments with impose of stronger magnetic field. Growth of Ra leads to domination of convective mode and hence inner wall become colder. Reduction impact of Nhs on Nu become more stronger when buoyancy force augments. In comparison with Ra, Nhs has no sensible impact on Be.
