Dissolution Extrusion Film Dynamics: Elucidating Film Characteristics and Fluid Dynamics Behavior

This research paper investigates the intricate interplay between molecular speed and squeeze dynamics within thin films. Utilizing the Reynolds equation as the foundational framework, we delve into the hydrodynamic pressure of thin films subjected to squeeze action. Through mathematical derivation and analysis, we unveil the nuanced effects of molecular speed on various layers within the film, shedding light on how these dynamics influence pressure distribution. Our findings reveal that increases in film thickness, porosity and sliding motion with molecular speed exhibit differential impacts on the hydrodynamic pressure with significant implications for understanding the behavior of thin films under squeeze conditions.
