Flow-induced vibration of piggyback cylinders
WebApr 11, 2024 · It is very important to suppress vortex-induced vibration of the flow field in a valve by optimizing the valve trim structure. In this paper, a multistage pressure-reducing valve is proposed, and the flow fields in the valve with the lightweight, flat bottom, circular truncated cone and cylinder valve plug are simulated using the ANSYS Workbench. WebApr 12, 2024 · Based on the two-dimensional hydrodynamic model of the finite volume method and structured multigrid, the flow characteristics around a square cylinder with boundary constraint are analysed. The gap ratio G/D (G is the distance from the cylinder to the channel boundary, and D is the side length of the square cylinder) does not change …
