Prevention of Cavitation in Propellers

It is well known that cavitation phenomena affect the efficiency of propellers. a major world wide economic problem for transport industry. The speed fast, ocean going vessels liimted by effects on hydrofoils and propulsion systems. main approaches industry to mitigate detrimental propellers restricted varying operating conditions, geometric design choice wear resistant materials. We here develop simple solution problem. has been over century dissolved gases reduce tensile strength liquids orders magnitude. De-gassing iquid dramatically reduces ability fluid cavitate. Propeller in ships submarines typically controlled reducing rotation rate and/or blade pitch. demonstrate astonishing fact can be completely prevented releasing de-gassed water adjacent low pressure side rotating propeller, without or Practical implementation cheap.
