Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0027] For three-dimensional problems, assuming that the fluid is an ideal fluid that is incompressible, inviscid, and rotatable, the velocity potential Φ(x,y,z,t) of the fluid motion satisfies the governing equation:
[0028]
[0029] Considering a linear harmonic with circular frequency ω, the velocity potential can be written as:
[0030] Φ(x,y,z,t)=Re[φ(x,y,z)e -iωt ] (2)
[0031] In the formula, Re means to take the real part of the variable; φ(x,y,z) is space complex velocity potential; t is time;
[0032] The spatial complex velocity potential φ satisfies the following governing equations and boundary conditions:
[0033]
[0034]
[0035]
[0036]
[0037] In the formula, the wave number of incident wave K=ω 2 / g; g is the acceleration due to ...
