EXP 1-4 Review of Studies
Axisymmetric drop impact dynamics on a wall film of the same liquid
Review of Experimental Studies and choice of test case
Provide a brief review of past experimental studies of this test case . Identify your chosen study and state the test case underlying the study, giving reasons for its choice ( e.g. a well-constructed test case, allowing good quality control and accurate measurements, of scientific and/or practical interest and as test case for CFD studies). Indicate whether or not the experiments have been designed for the purpose of CFD validation (desirable but not mandatory).
A reviews of experimental studies until 2016 is provided by Lang & Mudawar (2016)
In the literature, there are no experiments on the dynamics of the droplet-wall-film interaction for droplet impact on a wetted wall in the event that the process is rotationally symmetrical. Such data are highly relevant for the development of simulation methods, since the numerical effort remains limited compared to 3D calculations and extensive comparative studies can be carried out.
The experiments have been designed for the validation of CFD methods for numerical simulation of two-phase flows where the gas-liquid interface is well resolved.
