Effects of suction/blowing on thermal radiative magneto-micropolar fluid flow in a Darcy–Forchheimer porous medium

The problem discussed is related to the heat transfer analysis of the MHD micropolar fluid past a continuously moving stretching sheet with suction and blowing within a porous medium. Appropriate similarity transformations are obtained for the governing equations to convert PDE’s into ODE’s, which are then solved using the BVP4C process. The influence of crucial physical parameters such as surface mass transfer (blowing/suction), Prandtl number, inclination angle of the magnetic field, thermal radiation parameter, Darcy number and Darcy-Forchheimer parameter on the various profiles were examined. From the results, it is noted that magnetic fields can reduce the velocities, and increase the temperature of fluids owing to ohmic heating. Similarly, for the thermal radiation increase in the velocities and temperatures results, increasing the number of pores drastically affect the velocity boundary layer. The temperature of the fluid was also found to decrease at the boundary owing to the presence of the holes. The velocity decreased because the layer was thinned. From the numerical results, it was noticed that the skin friction coefficient increased by 247.3% and the Nusselt number decreased by 15.1% for $$\:M=1.5$$ than that of $$\:M=0$$ case. These results are discussed and compared with results from previous studies and a good agreement is found. This discovery could lead to advances in thermal management, porous heat exchangers, membrane filtration, geothermal power systems, plastics manufacturing, and magnetic fluid transport.
