Résumé

Valve dynamic analysis was examined only for the structural part or fluid part individually. In the work, ADNIA, the fluid structure interaction (FSI) was introduced to solve the valve dynamics considering heat transfer. The authors had performed the experiments to know the characteristics of valve dynamics and can obtain the dynamic behaviour of valves and pressure-volume diagram. FSI simulation was performed. It was conformed that the fluid structure interaction can explain the realistic valve dynamic behaviours. The advantage using FSI is that temperature and velocity profiles can be obtained. These data were difficult to get from the experiment, because of the inferior conditions inside the cylinder. With the obtained results, efficiency can be calculated. The authors applied the shape optimization technique using sequential quadratic programming to get the optimal design of suction reed valve.
