The cratering regime with its manifold characteristics like micro-entrapments, primary entrapment which could lead to the trampoline phenomena, vortex rings, micro-jetting and thick jets is chosen as a study case for the influence of liquid pool temperature on the drop impact into a deep pool. Characteristic drop impact which features micro-entrapments, primary entrapment and trampoline phenomena are selected as a test cases. Pool temperatures between 20 and 40 °C are studied, whereby the droplet temperature is kept constant. The experimental results are compared with simulations obtained using the interFoam solver of the OpenFOAM® open source CFD package.

Abstract
The cratering regime with its manifold characteristics like micro-entrapments, primary entrapment which could lead to the trampoline phenomena, vortex rings, micro-jetting and thick jets is chosen as a study case for the influence of liquid pool temperature on the drop impact into a deep pool. Characteristic drop impact which features micro-entrapments, primary entrapment and trampoline phenomena are selected as a test cases. Pool temperatures between 20 and 40 °C are studied, whereby the droplet temperature is kept constant. The experimental results are compared with simulations obtained using the interFoam solver of the OpenFOAM® open source CFD package.| File | Dimensione | Formato | |
