UNDERWATER NOISE ESTIMATION METHOD OF SAILING BODY, UNDERWATER NOISE ESTIMATION PROGRAM AND UNDERWATER NOISE ESTIMATION DEVICE

摘要

To provide an underwater noise estimation method, an underwater noise estimation program and an underwater noise estimation device estimating noise by a sailing body underwater by a combination of CFD and test result effectively and accurately.SOLUTION: Fluctuating pressure as underwater sound pressure by a sailing body is acquired by a combination of numeric value hydrodynamics (CFD) calculation and test result by: inputting noise estimation condition for a sailing body; carrying out numeric value hydrodynamics (CFD) calculation based on noise estimation condition of the sailing body; extracting a test result regarding the sailing body in a process of numeric value hydrodynamics and carrying out compensation by reflecting to the numeric value hydrodynamics (CFD) calculation.SELECTED DRAWING: Figure 2
