Bubble point pressure cryogenic systems

Ln addition, examination of Equation (3.16) shows that the current bubble point model does not account for variations in pressurant gas temperature, so warm gas data will be valuable for improving the prediction for cryogenic systems. Previous attempts were made to quantify the effect of warm gas on LAD degradation in the literature, but there were numerous reported inconsistencies in results as well as issues reported with the test apparatus. Historical attempts to quantify this effect are reserved for Appendix E. Clearly, carefully designed and controlled tests are required to accurately quantify the effect of warm pressurant gas on LAD performance.
