Optimization of the poppet valve

This article explains the design system based on the collaboration between the CFD solver SimericsMP and CAESES, based on actual research conducted!

The Italian company OMIQ SRL, which sells software, conducted research on an automatic design system using the poppet valve of high-pressure pumps developed by the Danish machinery manufacturer Danfoss. In this case, we will introduce the design system that integrates the CFD solver SimericsMP with CAESES based on the research that was actually conducted. The issue in this case is that the poppet valve exhibits unacceptable unstable behavior during operation. It was found that when the poppet valve attempts to open to its maximum displacement (27.5 mm), the instability of the flow increases, resulting in a decrease in pressure on the poppet valve, ultimately preventing the valve from fully opening (closing to about 6 mm remaining). This unstable phenomenon was verified through unsteady analysis using SimericsMP. *For more detailed information, please refer to the related link.
