Abstract: Galerkin finite element method is used to simulate the
flow field inside hydraulic control poppet valve at the conditions of
different openings, different structure of the valve body, different
size of the valve seat, the simulation results are given by visualizing
pictures. DPIV technique is used in experimental visualization, the
experimental results are good agreement with numerical results. It has
practical significance for us to design lower energy loss and lower
noise hydraulic control poppet valves.
Key words: Poppet valve Finite element method Flow field Visualization
