| dc.description.abstract | Supercritical flow instability in two vertical heated parallel channels was investigated experimentally and numerically using the Supercritical flow facility-Vertical (SFF-V) and a licenced 1-D non linear code CATHENA v3.5.4.4. The experiments were conducted with a range of system pressures from 7.4 to 9.1 MPa, inlet temperatures from 7 to 31 °C and various outlet k-factors. The working fluid used was CO2 driven via natural convection instead of a pump due to economic reasons. Total 16 cases of supercritical flow instability were obtained. The CATHENA code v3.5.4.4 was used to numerically model the instability boundary of the current experiments and also previous experiments conducted in China. The effect of wall thermal heat storage on instability boundary was also studied. | en_US |
