When calculating using the two-phase model, the phase transformation is modeled in addition to consideration of the two phases. The solubility of the air in the lubricant depending on the pressure and temperature is considered.

VGas,dissolved = VOil·αOil·pp0

VGas,dissolved Volume of the gas dissolved in the oil
VOil Oil volume
α​Öl Bunsen coefficient
p Pressure
p0 Ambient pressure

The Bunsen coefficient is a good approximation for the solubility of mineral oils classified as ISO-VG 32 through ISO-VG 200.
