Heat and mass transfer-driven multidimensional dynamics in squeezed flow configurations: An extensive investigation

The analysis of squeezing flow yields extensive applications in coating processes, polymer manufacturing, lubrication, microfluidics and biomedical engineering. It is essential for the optimization of biomedical devices, design of industrial equipment and advancement of material processing techniques. Based on the extensive applications of squeezing flow, this study aims to provide a concise explanation of the thermal rheological behavior of non-Newtonian Eyring-Powell fluid within the context of the squeezing flow phenomenon. The key dynamics through squeezing motion are scrutinized accounting for the impact of an innovative inclined magnetic field. For the comprehensive investigation of unsteady flow phenomenon, a horizontal channel with two heated parallel plates is taken. During squeezing mechanism, the movement of both plates towards each other and away from each other is briefly observed. Building on the modified Fourier's and Fick's laws, the mechanisms of thermal and mass transfers are deliberated via Cattaneo-Christov theory. The thermally radiative flow problem is further analyzed through the involvement of joule heating, chemical reactions, and heat generation/absorption. Through an effective bvp4c technique, numerical analysis is conducted for the present study. Different fields of flow problem are graphically manifested through 2D and 3D approaches influenced by pertinent parameters. This study yields the result that the velocity field exhibits dual behavior near the channel and away from the channel during squeezed motion. Moreover, as the squeezing parameter intensifies, the temperature field diminishes whereas the concentration field rises.
