Hydraulic propellor enhancement method by admitting air or gas through pipes using bernoulli principle and compressing in contracting nozzle exit

摘要

The present disclosure relates to a hydraulic propeller enhancement method for enhancing the propelling force of a hydraulic propeller 30, and uses a gas release outlet 40 in the propeller 32 at the area where the high-speed axial flow of water F passes for guiding in a gas by means of a negative pressure subject to Bemoulli's principle. Thus, subject to the principle, gas compressible characteristic and Boyle's law and the arrangement of the contracted end piece 341 of the nozzle 34 to work as an air compressor for compressing air bubbles 60, the invention uses one single gas guide device 50 and a negative pressure suction force to guide in air bubbles 60 to enhance the propelling force of the hydraulic propeller 30.
