Numerical Modelling of Evaporation Process in Cryogenic Systems
Samara National Research University, Heat engineering and heat engines Department, Samara, Russia
This article deals with a problem of evaporation numerical modeling in cryogenic systems of constant volume. Particularly, a method of nitrogen evaporation modeling in cryogenic fueling tank was considered. User-defined functions of nitrogen thermodynamic properties in temperature range of 70…400 K and pressure range of 0.1…30 MPa. The result of this research is calculation algorithm which allows to model processes of phase change in cryogenic systems with constant volume. A comparison obtained between results of numerical modeling with experimental and analytical data is presented. Deviation of results from experimental data is 5-10%.
