The current issue examines the effects of a non-uniform heat source, thermophoresis velocity, and activation energy on a Darcy-Forchheimer Powell Eyring towards a non-linear stretching sheet with changing thickness under the impact of variable thermal conductivity and spices diffusivity. Thermal conductivity and mass diffusivity in this issue are both intended to be linear functions of temperature and concentration. By using appropriate similarity variables, the flow system was turned into a system of PDEs for mathematical analysis, and subsequently into a system of ODEs. The Homotopy Analysis Method is used to arrive at the solution of the generated ODEs system. All important parameters' impacts are visually shown. A comparison with previous findings is done to corroborate the current findings. The temperature and concentration fields are enhanced while the velocity is depleted by the Forchheimer parameter. Temperature is increased by a non-uniform heat source and thermal conductivity characteristics. Thermophoretic velocity depletes the concentration while the spice diffusivity parameter increases it.
