Abstract
This article deals with the analysis of the thermal-diffusion effect, chemical reaction and heat generation on the convective hydromagnetic flow of water-based nanofluid past an instantaneously accelerated infinite vertical plate nested in a porous medium. Simultaneous application of
ramped temperature, ramped velocity, and ramped concentration has been considered. With the help of Laplace transformation, the set of transformed domain equations has been resolved. The consequences of various flow parameters involved in the study are analysed graphically. The results exhibit
that the hydrodynamic and solutal boundary layer elevates for the higher value of the Soret effect Sr. Moreover, the rate of heat transfer hikes and on the other hand, the rate of mass transfer drops on account of the volume concentration of nanoparticles φ. Again, it is observed
that the temperature, concentration and velocity field are dominated in the ramped condition by that of the isothermal condition.
