Investigation of Influence of Inflow Condition on Underwater Rotating Bodies Using Wall-Modeled Large Eddy Simulation
This study explores research methods for near-wall flow and pulsating pressure of underwater rotating bodies.First,the current state of research on numerical simulation methods for the near-wall flow of underwater rotating bodies is reviewed.Then,the wall-modeled large eddy simulation(WMLES)method is employed to simulate the near-wall turbulent characteristics and wall pressure fluctuations of underwater rotating bodies under different inflow velocities and inflow turbulence intensities.Turbulent kinetic energy,forces,axial velocity,and pulsating pressure are analyzed,along with the investigation of fluctuations in the turbulent flow at the bow of the rotating body.Finally,the mechanism of the influence of the inflow condition on the flow within the bow boundary layer is explored.
