In this article, we present the Laguerre wavelet exact Parseval frame method (LWPM) for the two-dimensional flow of a rotating micropolar fluid in a porous channel with huge mass transfer. This flow is governed by highly nonlinear coupled partial differential equations (PDEs) are reduced to the nonlinear coupled ordinary differential equations (ODEs) using Berman's similarity transformation before being solved numerically by a Laguerre wavelet exact Parseval frame method. We also compared this work with the other methods in the literature available. Moreover, in the graphs of the velocity distribution and microrotation, we shown that the proposed scheme's solutions are more accurate and applicable than other existing methods in the literature. Numerical results explaining the effects of various physical parameters connected with the flow are discussed.

An investigation of variable thermo-electrical field, viscosity, and thermal conductivity influence on blood rheological (Casson) fluid flow through micro annular channel subjected to suction/injection, slip, jump, and the nonlinear convective process is presented. The assumed steady, fully developed, and magnetized flow through the annular cylinder is modeled and non-dimensionalized under; Slip, jump, suction/injection conditions. Employing the Chebyshev collocation method, an approximate solution of the flow distributions is obtained. Parameters of interest indicate a declination of the flow field to a hike in variable thermal and electrical field parameters, appreciation to the risen value of viscosity parameter. Meanwhile, both momentum and energy distributions were promoted to a wider curvature radius.

“…Recently, a series of investigations of convective flow in a vertical annular porous medium have been carried out. Jha et al, 6 Oni and Jha, 7 Jha et al, 8 Yusuf, 9 and Jah and Yusuf 10 analyzed the transient free convective flow through the porous material; Isa et al 11 observed the steady‐state flow regime and time‐periodic boundary conditions through a vertical microcircular duct; and recently, Gireesha and Sindhu 12 performed the analysis on the heat absorption/generation of a Casson fluid flow through the annular microchannel. They established that a higher magnitude of Casson and Hartmann's number decelerates the fluid momentum, and that the heat‐generating parameter predicts the skin friction positively.…”

The nonlinear convection study on the flow of a dissipative Casson nanofluid through a porous medium of an inclined micro‐annular channel is presented. The cylindrical surfaces were conditioned to temperature increase and velocity slip effects. A uniform magnetic field strength was applied perpendicular to the cylinder surface. The heat source and Darcy number influence are explored in the examination of the blood rheological model (Casson) through the annular cylinder. Appropriate dimensionless variables are imposed on the dimensional equations encompassing Casson nanofluid rheology through an annular microchannel. The resulting systems of equations were solved and computed numerically via Chebyshev‐based collocation approach. Thus, the solutions of flow distributions, volumetric flow rate, and other flow characteristics were obtained. The result shows that both nonlinear convection parameters decrease the nanoparticle volume fraction, whereas they increase the energy and momentum distributions. Moreover, the volumetric flow rate is upsurged significantly by a wider porous medium, annular gap, a higher Casson parameter, and nonlinear convection influence.
