Abstract:
Blade coating is a techniquewhere blade operates as a typical smoothening toolto coat a fluid layer on the moving substrate. This study presents the heat transfer impact in blade coating process by employing the micropolar-Casson fluid with slip condition and viscous dissipation. The non-dimensional expressions are simplified by operating the Lubrication Approximation Theory (LAT). Analytical solution of the velocity, temperature and pressure gradient are obtained while numerical(root finding algorithm) used to acquire the pressure and other mechanical quantities. Impacts of coupling number, slip parameter, Brinkman number, microrotation, and Casson parameter on the various mechanical and flow characteristics are inspected through graphs and in tabular form. Micropolar effects decrease the coating thickness and increase the blade load while viscoplastic effects result give the opposite effect. Hence, these factors may help in efficient coating process and improving the substrate life.
