This article presents a numerical investigation of mass and heat transfer effects on an unsteady Magnetohydrodynamic (MHD) nanofluid flow in a permeable pipe. The influences of the chemical reaction and magnetic flux are considered. With the central finite-difference technique, the fundamental equations are discretized. The resulting equations are solved numerically using methods of lines, bvp4, and shooting methods. The influences of material factors on the solution are investigated and displayed through tabular and graphical illustrations. The study revealed that the Sherwood number, skin friction, and rate of heat transfer are all decreased by an increase in the magnetic field. Additionally, the rate of rise of the chemical reaction and Brownian motion is observed to reduce the concentration of the nanofluid. Furthermore, the study finds that the Soret number, porosity medium resistance parameter, and thermophoresis parameter all cause the concentration profile to climb; while, increasing the pace of the chemical reaction and brown mobility leads the profile to decline.
Key words: Chemical reaction, porous medium, magnetohydrodynamic (MHD, nanofluid.
