Three-dimensional transient simulation of Marangoni flow in a cylindrical enclosure under various gravity levels
Abstract
A numerical study is undertaken of the interaction between natural convection and Marangoni flow in a vertical cylindrical enclosure of aspect ratio 1, which has an adiabatic free lateral face and isothermal top and bottom walls. The 3D transient code uses a hybrid finite-difference scheme on a staggered grid with explicit time-steps, and an iterative pressure-velocity coupling. The flow patterns and isotherms are found to remain qualitatively unchanged in different gravity environments, and no significant disturbance of the axially symmetric flow mode is observed.
