The role of the CFD modelling in the shape optimization
of the pressure pulsations dampers

Abstrakt

Pressure pulsations in volumetric compressors systems have an important influence on the compression power and reliability. This problem occurs not only in huge compressor systems, as in the natural gas piping, in gas mines or national transport systems, but also in a small refrigeration compressors in domestic applications. Nowadays, it is necessary to develop pressure pulsation damping elements which will be effective for different mass flow rate values. One of the solutions are passive damping elements in the form of various types of nozzles. In addition to the decrease of pressure pulsations value, the result is also an increase in power consumption of the compression. Therefore, shape optimization is necessary. In the article the possibility of optimizing the shape of such elements using computational simulations is discussed.
