Modeling of the effect of air inclusions on pressure dynamics in a two-piston cylinder
In this example, the model demonstrates the effects caused by air inclusions in a liquid during operation of a two-piston cylinder. The absolute pressure does not fall below zero, since the volumetric modulus of elasticity of a homogeneous gas-liquid mixture decreases accordingly at low pressures.
