Abstract
Hydromagnetic Couette-Poiseuille flow of variable viscosity nanofluids with heat and mass transfer between two parallel plates in a rotating permeable channel is investigated numerically. The model nonlinear problem which incorporates thermophoresis, Brownian motion, viscous dissipation, Joule heating and Hall effects are obtained and tackled numerically using a fourth order Runge–Kutta–Fehlberg integration scheme with shooting technique. The effects of various thermophysical parameters on nanofluid velocity, temperature, concentration, skin friction coefficient, and Nusselt and Sherwood numbers are discussed thoroughly and analyzed through graphs. The results show that Hall current significantly affects the flow system. Results for some special cases of the present analysis are in good agreement with the existing literature.
