Gravity-driven thermoviscous liquid film down a heated or cooled vertical cylinder
Sana Khanum, Naveen Tiwari
Abstract
Gravity-driven flow of a liquid over an isothermal cylinder is unconditionally unstable. The flow of a thermoviscous fluid over a heated or cooled substrate shows interesting stability behavior. The relevant parameters in the model affect the spatiotemporal nature of the instability.
