“…Since, the ratio of momentum diffusivity to thermal diffusivity of the fluid is characterized by the Prandtl number, P r ¼ 1 represents fluids whose thermal boundary layer thickness and momentum have the same order of magnitude. For all values of P r except P r ¼ 0; the temperature as well as the velocity solutions in Equations ( 31) and (32), respectively, are valid. It must be noted that P r ¼ 0 is not possible in practice and therefore has no effect in the solution obtained.…”

“…They noticed that increasing values of Soret number increased the fluid concentration and velocity. Konwar et al [32] built on Hussanan et al [31] work's to consider an MHD heat and mass transfer of a Newtonian fluid mixture on an exponentially stretched sheet in porous medium with temperature-dependent fluid properties, Soret and Dufour effects. They observed that flow, heat, and mass transfer are significantly influenced by mixed convection parameters, magnetic field, permeability, conductivity, Prandtl number, viscosity and Schmidt number.…”

This paper addresses the unsteady hydrodynamic convective heat and mass transfer of three fluids namely air, water, and electrolyte solution past an impulsively started vertical surface with Newtonian heating in a porous medium under the influences of magnetic field and chemical reaction. Suitable dimensionless parameters are used to transform the flow equations and the approximate analytic method employed to solve the flow problem. The results are illustrated graphically for the velocity, temperature, and concentration profiles. Though, low Prandtl numbers produce high-thermal boundary layer thickness, however, as a novelty, the presence of the magnetic field delayed the convection motion hence, the thermal boundary layer thickness is greater for water with high Pr = 7.0 as compared to air with low Pr = 0.71 and electrolyte solution with low Pr = 1.0. Practically, water with a high-Prandtl number can effectively absorb and release heat. This makes water useful in applications such as geothermal heat pumps and solar thermal collectors, industrial processes such as chemical reactions, distillation, and drying, and in oceanography in predicting the movement and behavior of ocean currents, which in turn can impact weather patterns and climate. Another major observation from the study is that the rate of cooling associated with air, water, or electrolyte impacts differently on the product being cooled.
