Cavitation simulation based on computational fluid dynamics (CFD) has become very popular at the design stage
of hydromachinery. However, there are not many publications reporting on cavitation simulations in real industrial applications
such as pumps, turbines, marine propellers, and valves. This makes it difficult to assess the validity of current cavitation CFD
for these purposes. Generally, it is believed that the accuracy of the current cavitation models is insufficient even for the
steady hydraulic performance in such complex machines. Much more is known about modeling capabilities of fundamental flows like
cavitation bubble dynamics or the behavior of single or multiple bubbles in typical 2D/3D devices like nozzles and hydrofoils.
It is the objective of this forum to bring both fields of research together.
This forum aims at gathering, exchanging and sharing information from researchers and engineers actively working on the development and the application of cavitation CFD for both the fundamental and industrial applications. All accounts of using cavitation simulation are welcomed to be presented. Examples include industrial applications, prediction of cavitation performance, cavitation instabilities, cavitation noise and vibration, and cavitation erosion. Since the progress in cavitation modeling relies heavily on two-phase flow modeling, turbulence modeling, and fluid-structure interaction, researchers in these areas are also encouraged to submit.
