RÉSUMÉ

Nanofluids, as regards their marvellous enhancement in thermal conductivity, have become useful in several industrial and medical applications. This study presents an analysis of flow, heat and mass transfer for unsteady nanofluid flow through orthogonally moving porous disks. The Buongiorno theoretical phenomena of nanofluids subject to heat and mass transfer of nanoparticles have been designed mathematically for orthogonally porous disks. The fluid is thought to be non-Newtonian, whose flow is described by the mathematical model of a Casson fluid. Governing partial differential equations (PDEs) are reduced to nonlinear ordinary ones which are solved numerically by utilizing the shooting technique. The influence of some parameters on the velocity and thermal distributions with physical quantities like skin friction coefficient, Nusselt and Sherwood numbers has been studied through graphs and tables.
