Hall Current and Radiation Effects on Unsteady MHD Squeezing Nanofluid Flow in a Rotating Channel with Lower Stretching Permeable Wall

摘要

In analysis of present model, we have analyzed the Hall current and radiative effects on unsteady MHD squeezing nanofluid in a rotating channel. The lower wall is permeable and linearly stretching, and the upper wall is squeezing downward in the presence of MHD. By introducing similarity transformation, we get the ordinary coupled differential equation. The transformed nonlinearly coupled differential equations are solved numerically by bvp4c solver using software MATLAB. We have taken nanoparticles of copper (Cu) and alumina (Al_2O_3) as base fluid (water). The effect of different parameters such as magnetic field parameter M, squeezing parameter Sq, rotational parameter ω, suction parameter w_0, nanofraction parameter Φ, hall current parameter β_e, radiation parameter N on velocity profile, and temperature profile is displayed through tables and graphs.
