Hydrothermal and mass impacts of azimuthal and transverse components of Lorentz forces on reacting Von Kármán nanofluid flows considering zero mass flux and convective heating conditions

An inclusive examination has been carried out numerically to explore the multiple physical prominences of steady MHD Von Kármán's flows of chemically reacting nanofluids that can be occurred over a rotating disk in the presence of a radially applied magnetic field, in the case where the disk surface is impermeable and heated convectively, in which the vertical nanoparticles’ mass flux has vanished practically. By applying the revised Buongiorno's formulation and Von Kármán's approach, the foremost conservation equations are derived properly in the context of the boundary layer theory. By applying an efficient differential quadrature algorithm, the boundary layer equations are treated numerically to generate accurate outcomes. As upshots, it is found that the nanofluid flow slows down meaningfully with the increase in the magnetic parameter. Significant enrichment in the temperature distribution and wall nanoparticles’ molar concentration can be achieved by mounting the magnetic parameter, the Schmidt number, and the chemical reaction parameter, whereas, the Prandtl number shows a reverse trend. It bears mentioning here that the convective heating reinforces the occurrence of the thermophoresis process.
