Optimization of Structure and Calculation of Flow-Force on Poppet Valve under Converging Flow

Article Preview

Abstract:

This paper optimizes the structure of the poppet valve based on the internal flow. The flow-force on poppet valve in the case of the converging flow is simulated and studied by CFD. Simulation results represent that the traditional formula for computing the flow-force can be used only in the certain range, so the formula is modified based on the simulation result.
