Abstract
The present research provides numerical handling of a laminar flow mixed-radiation interaction convection heat transfer within two-sided wavy enclosures containing adiabatic obstacles. The convection process is due to the movements of the enclosure side walls together with the difference in temperature and density. Two designs of the flow domain are recognized, namely, a wavy enclosure containing a square obstacle (D1) or including a cylindrical obstacle (D2). Both the flow domain and the magnetic field are inclined with different angles and impacts of the thermal radiation and heat absorption(generation) are conducted. The Galerkin Finite Element Method associated with the Characteristic-Based Split approach is utilized to solve the governing system. The prime outcomes detected that the growth of the radiation and heat generation parameters enhances the convective process. Also, the increase in the magnetic parameter causes a dominance of the nanofluid friction irreversibility compared to the heat transfer one.
