Fluctuating pressure measurement and cavitation observation of tug type pod propulsion in cavitation tunnel

For the key technology of pod propulsion,experimental investigation of fluctuating pressure measurement and cavitation observation for tug type pod propulsion is carried out in cavitation tunnel of Naval University of Engineering.Cavitation development and change of pod propulsion propeller model is observed under different operating conditions,the result is recorded by manual cbservation method.At the same time fluctuating pressure is measured through the fluctuating pressure sensor installed above the propeller.The experiment results are analysed in detail and discussed the characteristics and laws of puller type pod propulsion’s cavitation performance and fluctuating pressure under different working conditions,which can provide reference value for pod propulsion’s performance and design research.
