Analysis of Magnetohydrodynamic Micropolar Nanofluid Flow due to Radially Stretchable Rotating Disk Employing Spectral Method

The present analysis is aimed at examining MHD micropolar nanofluid flow past a radially stretchable rotating disk with the Cattaneo-Christov non-Fourier heat and non-Fick mass flux model. To begin with, model developed in form of nonlinear partial differential equations (PDEs) for momentum, microrotation, thermal, concentration their boundary conditions. Employing suitable similarity transformation, layer flows governing these PDEs are transformed into large systems dimensionless coupled ordinary (ODEs). These ODEs solved numerically by means spectral local linearization method (SLLM). consequences more noticeable involved parameters on different fields engineering quantities interest thoroughly inspected, results presented via graph plots tables. obtained confirm that SLLM stable, accurate, convergent, computationally very efficient to solve system equations. radial velocity grows while tangential velocity, temperature, distributions turn down as value stretching parameter improves, hence, practical applications, helpful advance cooling process disk. occurrence microrotation viscosity ( A 1 − 6 ) declines profile, kinetic energy fluid reduced some extent far away from surface novelty study consideration microscopic effects occurring elements such micromotion couple stress, non-Fourier’s non-Fick’s flux, effect flow, heat, transfer.
