Bénard-Marangoni convection instability occurs as horizontal layer of silicone oil with aluminum flakes is heated from the bottom with a free surface on top. Variations in temperature cause surface tension gradients that drive the flow.May 20, 2014FlowVis@CU02014, 2014 Team First, Convective Cell, Flow Categories, Flow Vis Techniques, Images, Media, Rheoscopic Fluid, Surface Tension, z Class & Assignment
