THE PHYSICS OF PULSATIONS - PART II: A Method to Provide Accurate Prediction of Pulsation Magnitudes Critical to Compressor Station Design

摘要

The differences between the full Navier-Stokes and the Acoustic Wave equations can be demonstrated using case studies. Several case studies are presented, here to demonstrate the differences in the two equations. Specifically, the effects of dynamic velocity and damping in the Navier-Stokes equation are contrasted with the Acoustic Wave equation, which does not contain these terms. The following case studies were run using the TAPS solver with full Navier-Stoke implementation and an equivalent time domain acoustic solver.
