Heat transfer augmentation using nanofluids in an elliptic annulus with constant heat flux boundary condition

This work reports numerical simulation for three dimensional laminar mixed convective heat transfers at different nanofluids flow in an elliptic annulus with constant heat flux. A numerical model is carried out by solving the governing equations of continuity, momentum and energy using the finite vo...
