heat transfer characteristics of hybrid nanoparticles in newtonian fluid inside a channel with airfoil: a cfd simulation using comsol multiphysics

Current study aims to investigate flow and heat transfer in a converging diverging channel for compressible nanofluid. an airfoil-shaped steel fragment is used as an internal obstetrical before flow enters to assess its impact on flow behavior and heat transfer. for nanofluids in-compressible newtonian fluid is assumed as a base fluid. hybrid nanofluid model is applied to develop the governing flow equation. the computational fluid dynamics tool i.e. comsol multiphysics is applied to simulate a variety of boundaries including inlet and outlet conditions, no-slip and slip conditions etc. a triangular mesh is created using comsol multiphysics. the contour plot of momentum and thermal boundary layer are examined. the effects of the contraction and the steel fragment on the fluid’s velocity, pressure, temperature and convection of heat are also addressed.
