Importance of exponentially falling variability in heat generation on chemically reactive von kármán nanofluid flows subjected to a radial magnetic field and controlled locally by zero mass flux and convective heating conditions: A differential quadrature analysis

Owing to the various physical aspects of nanofluids as thermally enhanced working fluids and significance swirling flows in rheological devices well spin coating lubrication applications, current comprehensive examination aimed explore important features spinning chemically reactive Newtonian over a uniformly revolving disk existence radially applied magnetic field along with an exponentially decaying space-dependent heat source, case where surface is heated convectively unaffected by vertical nanoparticles’ mass flux. Based on feasible boundary layer approximations Buongiorno’s nanofluid formulation, leading coupled differential equations are stated properly sense Arrhenius’s Von Kármán’s approaches. By employing advanced generalized quadrature algorithm, obtained handled numerically higher order accuracy generate adequate graphical tabular illustrations for different values influencing flow parameters. As findings, results confirm that motion decelerates meaningfully thanks resistive influence. A significant thermal amelioration can be achieved strengthening impact, generation heat, convective process, thermophoresis mechanism. Moreover, it found thermo-migration nanoparticles reinforced more via intensification nanoparticles, activation energy.
