摘要

Unsteady extracellular fluid (ECF) flow along with a rotating infinite vertical porous plate in the presence of a transverse magnetic field has been studied numerically. The dimensional governing equations have been non-dimensionalized by useful dimensionless variables. The explicit finite difference method has been used to solve dimensionless equations. The numerical results have been calculated by studio developer FORTRAN 6.6a and MATLAB 2018a. For perfect conducting case, Magnetic Diffusivity Parameter <span style="white-space:nowrap;">5 <span style="white-space:nowrap;">≤</span><em> P</em><em>_m </em><span style="white-space:nowrap;">≤ </span>15</span> has been taken in induction equation. For good accuracy, stability and convergence analysis have been analyzed. Mesh Sensitivity test, steady-state solution test, and code validation test have been performed. For time step<em> </em><em></em><span style="white-space:nowrap;"><em><span style="white-space:nowrap;">&#964;</span></em></span> <span style="white-space:nowrap;">= 1</span>, the numerical results have been found for the primary velocity, secondary velocity, angular velocity, primary induced magnetic field, secondary induced magnetic field, temperature as well as shear stresses along <em>x</em> and<em> z</em> direction, couple stress along<em> z</em> direction, current densities along <em>x</em> and <em>z</em> direction and the Nusselt number. Finally, the effects of various parameters have been separately discussed and illustrated graphically.
