The PBCF has been developed and commercialized in 1987 by the corporate group centered in Mitsui O.S.K. Lines, Ltd.. PBCF is the originated device to be focused in the recovery of energy from the flow out energy in propeller hub vortex. Its fundamental mechanism and effects have been repeatedly verified through numerous series of model tank tests and actual ship measurements from the first stage of the development. The 5% energy saving effect has been presented on numerous occasions at academic association meetings both in Japan and overseas, and this has been well accepted both in Japan and overseas.


Basic principle of PBCF effect As the flows accelerated down after the blade trailing edges are blocked and rectified to a straight ship-stream by the fins of the PBCF, the hub vortex will be eliminated.
