摘要: Abstract In this paper, natural convective heat transfer in a differentially heated square porous cavity filled with nanofluid and using two-temperature model for the Tiwari Das has been studied numerically. The employed allows us to analyze fluid flow when solid matrix are not local thermal equilibrium. boundary value problem formulated, terms of dimensionless stream function temperature matrix, solved numerically second-order accurate finite difference method. Based on results obtained, adding nanoparticles base suppresses flow. Further, it is concluded that reduces as nanofluid/solid-matrix interface parameter reduces.
