Abstract: The purpose of this study is to study the combined influence of thermal and mass stratification on unsteady magnetohydrodynamic nanofluid past a vertically oscillating plate with variable temperature. The problem’s governing equations are numerically solved using the implicit Crank-Nicolson approach. Significant results from the thermal and mass stratification are contrasted with the environment where stratification is absent. The velocity decreases with both kinds of stratification, while the temperature decreases with thermal stratification and the concentration decreases with mass stratification. We use graphs to demonstrate the effects of the different parameters, including phase angle, thermal radiation, magnetic field strength, heat sources/sinks, and chemical reactions. Additionally, the Skin-Friction Coefficient, the Nusselt Number, and the Sherwood Number are computed and represented graphically. The findings highlight the critical role of stratification in improving fluid dynamics and increasing the efficiency of heat and mass transfer processes,providing essential information for engineering and environmental applications under similar circumstances.
