Subject area: Science,Engineering and Technology · Area of research: Computational Fluid Mechanics

Abstract
This research examines free convection heat and mass transfer in a slip flow regime incorporating thermo-diffusion (Soret) effects. The governing equations for momentum, energy, and concentration were first constructed in dimensional form and then converted into their respective non-dimensional system with suitable similarity variables. The coupled non-linear differential equations were solved using the regular perturbation technique to obtain analytical solutions, resulting in expressions for the velocity, temperature, and concentration fields. The findings indicate that the diffusion-thermo parameter improves both the temperature and velocity of the fluid, indicating an augmentation in thermal energy transfer attributed to the Soret effect. The slip parameter and suction/injection (substation) parameter were shown to considerably affect the increase in the velocity profile, enhancing fluid motion over the surface. In contrast, an increase in the Schmidt number and Prandtl number demonstrated a reduction in fluid velocity due to enhanced resistance to momentum and mass diffusion. The work illustrates how thermo-diffusion and slips circumstances alter free convective transport characteristics, offering valuable insights for micro-flows, energy systems, and engineering processes related to heat and mass diffusion.
