Shock Waves from Non-linear Wave Steepening

Wave steepening is a non-linear wave propagation effect that arises for strong pulsation in bubbly liquids, e.g. as is the case for reciprocating pumps and water or oil based mud. Steepening form repetetive shocks and may adversely affect pump equipment and piping fatigue life. To understand this shock generating mechanism, we must first better understand what is implied by the phrase Pressure. There are three pressure components: Line Pressure  (LP) Kinetic Pressure (KP) Pulsation Line Pressure is the stationary part of the pressure, Kinetic Pressure is pressure that moves with the flow...
