Thin film flows on a linearly moving surface with thermocapillary effects and variable heat generation/absorption

Current research focuses on thin liquid films on a linear stretching sheet, taking into account the effects of thermocapillary, magnetic fields, thermal radiation, viscous dissipation, and variable heat generation/absorption in a porous media. Similarity transformations are used to turn the governing equations into a set of linked ordinary differential equations (ODE). The coupled ODEs regulating motion, heat, and mass are numerically solved. The experiment's results reveal that different factors affect mass transfer, temperature, and velocity differently. These effects are addressed by a detailed analysis and graphical representations, which indicate that the flow temperature decreases consistently with increasing thermocapillary number, By understanding thermocapillary flow interactions, industries can enhance coating efficiency, uniformity, and thermal management, whereas the velocity profile initially slows, then increases. These data shed important light on the intricate dynamics including mass transfer, temperature, and velocity.
