- W4352991098 abstract "Vortex is one of the complex contents of fluid dynamics. The traditional first-generation vortex ‘Q-criterion’ and second-generation ‘vorticity’ have various problems in calculation. The third-generation vortex recognition ‘Rortex’, which is more in line with the actual laws of physics, came into being. Based on the third-generation vortex recognition technology, this paper conducts a detailed analysis of the propeller tail vortex on the OpenFOAM platform. Taking the DTMB4119 propeller as the research object, the wake characteristics of the propeller are studied by comparing the wake vortex considering cavitation and ignoring it. The development process is qualitatively analyzed in axial velocity, turbulent kinetic energy, turbulent viscosity and so on. Besides, since the vortex is an important source of noise, the acoustic characteristics is analyzed by acoustic analogy. Combined with the vortex distribution, this paper is committed to explaining the influence of the vortex on the linear and nonlinear terms of the propeller noise. The results show that the third-generation vortex recognition technology can remove the shear in the flow field and the spurious vorticity near the boundary, so that the continuous vorticity calculated by the Q criterion becomes a separated vorticity, which is more in line with the actual laws of physics. At the same time, the cavitation affects vorticity and nonlinear sound source, which increases the overall sound pressure level." @default.
