Modeling wave processes at the outflowing of a water coolant with supercritical initial parameters

The effect of outflowing water coolant with supercritical parameters on a barrier

“…On the PV-diagram with initial P 0 =23 MPa and T 0 =370 0 С, the adiabatic line passes to the left of the critical point and crosses the line of boiling, i.e. enters the two-phase region with void fraction equal to null [7]. In the case when the initial parameters take values P 0 =23 MPa and T 0 =380 0 С, the adiabatic line passes to the right of the critical point and crosses the line of condensation, i.e.…”

Modeling the outflow of liquid with initial supercritical parameters using the relaxation model for condensation

“…If in the stationary mode both pressure and temperature are supercritical (p > p CR , T > T CR ), it is possible for fluid parameters to approach the binodal (boundary of "single-phase and two -phase" region) from the condensation curve [2]. The process of adiabatic expansion, as a rule, is non-equilibrium, and thermodynamic non-equilibrium two-temperature model of steam-water mixture motion is frequently used for its description [3].…”
