  A Systematic Review on Turbo-Machinery Cavitation Analysis and Thermodynamic Effects
  Author(s): Omer Haitham Kanam, Maher Obaid Ahmed and Qasim Yahya Rahawi
  
  Cavitation is a word that widely famous in the field of hydraulic machines design and operation. It is undesirable cause a massive wear effect on the impeller?s blades, noise, vibration, and reduction in efficiency. This review article is outlined the development in interpretation of cavitation control and the methods (governing equations, CFD technique, vibration analysis, and obstacle effects) used formerly with its mathematical analysis. Most articles agreed with simulation of basic equations using CFD\CFX software, their results were the rule to optimize the pump?s efficiency by reducing cavitation as compared to the studies which were used numerical method only. The pressure and velocity distribution in a volute, height of obstacles and cavitation coefficient parameters are also explained briefly. A thermodynamic effect was found to be interest to cover because it?s influencing the .. View More»
