Résumé

Simulation is one of the useful methods to evaluate a compressor. Simulating the flow in the compression chamber is a necessary technique to evaluate the performance and reliability of the designed compressor, and building a CFD analysis technique that can output data in three-dimensional space can capture the flow in the compression chamber more accurately. In this calculation, the compression chamber of a swing compressor is calculated by CFD, and the results of simulating the compression process are reported. The general purpose calculation code CONVERGE was used for the calculation. In this calculation, the compression chamber and the muffler space behind it were modeled. The computational space before and after the compression chamber was connected to reduce the pressure reflection generated by the calculation. The actual geometry of the discharge valve was used, and the calculation was performed using the beam behavior of the FSI. By calculating the valve behavior using the beam behavior instead of the spring-mass behavior, we thought that the behavior would be more consistent with the actual machine. As a result of the calculation, the pressure change in the compression chamber and the behavior of the discharge valve were output and compared with the results measured on the actual machine. From the comparison results, it was confirmed that the calculated results of CFD represented the characteristics of the actual machine.
