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…

Entropy generation and jet engine optimization
TLDR
In 2009, it was shown that a phenomenological model was realized in order to compute some of the physical parameters needed for the design of the most common technological applications with an economical saving in planning.
Experimental study of a cavitation heat generator
Recent research has investigated the use of ultrasonic or hydrodynamic cavitation for chemical reactors, water treatment equipment, and heat generators. In this article, a new cavitation heat
Entropy generation analysis for the cavitating head-drop characteristic of a centrifugal pump
Cavitation is a challenging flow abnormality that leads to undesirable effects on the hydraulic behaviour of centrifugal pumps. This study analyses the cavitating flow at a normal flow rate using the
Bio-engineering thermodynamics: an engineering science for thermodynamics of biosystems
TLDR
A review of the recent results obtained by using the approach proposed is proposed in order to highlight its thermodynamic fundamental: it could be the beginning of a new engineering science, the bioengineering thermodynamics.
Non-equilibrium Thermodynamic Extension of the Phenomenological Theories of First-order Phase Transitions
Because the phenomenological theories of phase transitions which are based on the equilibrium thermodynamics cannot describe the first-order phase transition processes accurately, the non-equilibrium
