This study examines the heat transfer effects in blade coating process and investigates the influence of various factors on the coating process and substrate life.
Blade coating is a technique where blade operates as a typical smoothening tool to coat a fluid layer on the moving substrate. This study presents the heat transfer impact on the 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, whereas viscoplastic effect results give the opposite effect. Hence, these factors may help in an efficient coating process and improve the substrate life.
