Hydrodynamic cavitation: from theory towards a new experimental approach
@article{Lucia2009HydrodynamicCF, title={Hydrodynamic cavitation: from theory towards a new experimental approach}, author={Umberto Lucia and Gianpiero Gervino}, journal={Central European Journal of Physics}, year={2009}, volume={7}, pages={638-644} }
Hydrodynamic cavitation is analysed by a global thermodynamics principle following an approach based on the maximum irreversible entropy variation that has already given promising results for open systems and has been successfully applied in specific engineering problems. In this paper we present a new phenomenological method to evaluate the conditions inducing cavitation. We think this method could be useful in the design of turbo-machineries and related technologies: it represents both an…
