Investigation of Lorentz forces and radiation impacts on nanofluid treatment in a porous semi annulus via Darcy law

Influence of Lorentz forces and radiative term on nanoparticles treatment through a porous semi annulus has been displayed in current article. An innovative numerical method was employed to portray the roles of radiative term, Rayleigh number and Lorentz forces. Working fluid is Al2O3-H2O nanofluid with various shapes. Results display that inner wall temperature reduces with rise of Rd. The best shape of nanoparticle in view of hydrothermal treatment is Platelet shape.
