Abstract：

The　cavitation　flow　characteristics　in　jet　pipe　amplifier　with　different　nozzles　were　simulated　using　commercial　computational　fluid　dynamics　(CFD)　software.　The　influence　of　operating　parameters　and　structural　parameters　of　jet　nozzles　on　cavitation　jets　are　the　key　objective.　These　parameters　mainly　include　inlet　pressure,　outlet　pressure,　temperature　of　water,　nozzle　convergence　angle,　the　length　of　the　nozzle　cylindrical　section,　nozzle　diameter　and　nozzle　export　chamfer　angle.　The　results　provide　methods　to　limit　the　emergence　and　development　of　the　nozzle　jet　internal　cavitations.　©　(2012)　Trans　Tech　Publications,　Switzerland.
