Summary
By definition, a fluid machine is a device which converts the energy stored by a fluid into mechanical energy or vice versa. Relevant examples are pumps, water turbines and marine propellers. The flow associated with these units is often of a multiphase nature given the involvement of various fluids and materials (such as water, gases of different types and sand or other granular materials). In turn, these can give rise to a variety of behaviors, phenomena and related “working conditions”, which can seriously affect the safe and stable operation or exploitation of these systems. Relevant research is therefore still needed to promote the development of this specific field of engineering. Relevant scholars are invited to contribute to this Special Issue by submitting their recent work on the analysis of such multiphase flows and related “vortex dynamics”. In addition to the presence of different phases, indeed, the flow “vorticity” (being present as a result of the turbulent nature of the flow or due to other mechanical effects) is also expected to play a crucial role in fluid machinery. Relevant subjects include (but may not be limited to):
· Experimental and numerical investigations of multiphase flow in fluid machinery;
· Cavitation flow in hydraulic machinery
· Vortex dynamics in fluid machinery
· Vibration, noise, fatigue and damage analysis
In all cases, the submitted paper is expected to provide indications or recommendations for the design and optimization of these systems.
