CALCULATION OF THE PRESSURE PULSATIONS IN AN EXPANSION JOINT OF A PIPELINE THROUGH WHICH A LIQUID IS PASSED

The pressure pulsations in a working liquid fl owing through an expansion joint of a pipeline in a power installation were calculated. The vibration of the path of such an installation and the nonstationary fl ow of a compressible liquid in it were simulated with the use of original methods of the computational fl uid dynamics and moving meshes. The calculation data obtained are in good agreement with the corresponding results of a natural experiment and numerical predictions made on the basis of a simplifi ed analytical model.
