Witryna1 wrz 2002 · The fakir regime has another interesting feature: because the substrate supporting the drop consists mainly of air, the usual surface defects are largely … Witrynasure. The drop can follow two successive deformations se-quences prior to impalement. First, the fakir drop remains on top of the asperities of the rough surface and increases its curvature as the drop evaporates. Then, impalement is locally nucleated by a defect and lead to the growth of a partly impaled region below the drop where the liq-

This reduction occurs for spatially modulated heating and is associated with the formation of separation bubbles which isolate the main stream from direct contact with the solid wall. small white house exterior
