The aim of this research is to investigate the combined effects of thermal and mass stratification on unsteady magnetohydrodynamic nanofluid moving through an exponentially accelerated vertical plate in a porous medium. The governing equations of the problem are solved numerically by using the implicit Crank–Nicolson method. The results of the nanofluid with two different stratification are compared to those obtained without any stratification. The velocity of the nanofluid decreases with both types of stratification, whereas temperature and concentration decrease with thermal stratification and mass stratification, respectively. A variety of parameters, including the volume fraction of nanoparticles, thermal radiation, heat source/sink, and chemical reaction, can be studied using graphs. The important results demonstrate that nanofluids are more thermally conductive than normal fluids. This research holds significant implications in various fields, including power generation, electronic component cooling, and vehicle construction.
