Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification

Yuanzineng kexue jishu, 2022
When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.
