Theoretical Study of Thermal and Mass Stratification Effects on MHD Nanofluid Past an Exponentially Accelerated Vertical Plate in a Porous Medium in Presence of Heat Source, Thermal Radiation and Chemical Reaction

This research work investigates the impacts of thermal and mass stratification on unsteady magnetohydrodynamic nanofluid moving through a vertical plate that accelerates exponentially with variable temperature in a porous medium. The governing equations of the problem are solved numerically by using the implicit Crank Nicolson method. We compare the results obtained for the nanofluid with two distinct stratifications to those obtained with no stratification. The nanofluid's velocity decreases under both types of stratification, while temperature drops under thermal stratification and concentration reduces under mass stratification. We explored a wide range of factors using graphs, including the volume fraction of nanoparticles, thermal radiation, heat source/sink, and chemical reaction. The significant findings indicate that nanofluids exhibit higher thermal conductivity compared to conventional fluids. The current study has enormous significance in several domains, such as power generation, electronic component cooling, and vehicle construction.
