Experimental investigation of hybrid contra-rotating shaft pod propulsor in the cavitation tunnel
In order to analyze the interactions among various components of hybrid contra-rotating shaft pod (HCRSP) propulsor and effects of test devices, the model test of HCRSP propulsor was conducted in a cavitation tunnel. In the present study, the interactions among fore propeller, aft propeller and the pod of HCRSP propulsor are analyzed with the influence of long-axis dynamometer. It is found that long-axis dynamometer shows great influence on pod propulsor which is made up of a pod and an aft propeller, but little influence on the fore propeller. Especially, under the condition of using long-axis dynamometer or not, the difference of thrust coefficient and torque coefficient of aft propeller with high advance coefficient reached 10%. Besides, fore propeller could accelerate the flow of pod propulsor. In detail, the pod and aft propeller show blocking and suction effect respectively, and these impacts could cancel out each other within a certain range.
期刊介绍：
For the past 20 years, Fluid Mechanics Research (prior to 1992 Fluid Mechanics-Soviet Research) has offered broad coverage of the entire field of fluid mechanics including flow of compressible and incompressible fluids, vapor-liquid and slurry flows, turbulence, waves, boundary layers, wakes, channel and nozzle flow, fluid-structure interaction, lubrication, flow in porous media, flow through turbo-machinery, aerodynamics and rheology as well as new and innovative measurement techniques. The journal''s coverage is now being broadened to encompass research in the general area of transport phenomena where convective, diffusional and chemical reaction processes are important and to include biological systems as well as technological and geophysical systems. Fluid Mechanics Research has now merged with the TsAGI Journal, a publication of the world-famous Central Aero-Hydrodynamics Institute in Russia. This will position the new International Journal of Fluid Mechanics Research (IJFMR) as a leading journal on the art and science of transport phenomena and its application to the understanding of complex technological systems while maintaining a balance between academic materials and practical applications.
