Investigation of drop and spray impingement on a thin liquid layer accounting for the wall film topology

Beschreibung

The single drop impingement processes upon steady and wavy liquid surface films of finite thickness and the spray impingement process onto rigid walls was studied both experimentally, as well as computationally and analytically. The global aim of the present study was to develop a mathematical model of the single drop and spray impingement process onto liquid wall films. To achieve this aim, the focus was put in particular on the description of the hydrodynamics of the wall surface film produced by spray impingement onto the wall, on a broader understanding of the physics involved in modeling of spray impingement processes and on the formulation of mathematical models based on experimental data and numerical simulations of the single drop impingement.
