Point/line heat source configuration with buoyancy and soret effect in a free convective radiative flow over a vertical channel

The present study evinces a comprehensive analysis of heat and mass transfer within a vertical channel, influenced by point/line heat source configuration, thermal radiation, the soret Effect, the buoyancy effect, and the incorporation of suction/injection phenomena. The uniform heat source utilizes the Heaviside step function, adapted for point/line heat source configuration. The governing ordinary differential equations describing the flow are systematically addressed using the Laplace transform technique. Contour plots illustrate the influence of Soret and buoyancy on velocity and concentration profiles, while a 3D temperature plot demonstrates the impact of radiation parameters influenced by point or line heat source on temperature distribution. Based on the findings of this study, as the Soret effect intensifies, there is a notable augmentation in the rate of mass transfer. Also, as radiation levels rise, there is an approximately 26% increase in the heat transfer rate at the left wall, while a contrasting trend is noticed at the right wall. The outcomes of the research are carefully analyzed and compared with existing literature, and the present findings seamlessly correspond with the established research in the literature.
