Pulsationen bei der Druckentlastung von ReaktorenLucas, D.
During two-phase blowdown from pressure vessels considerable pulsations of the discharged mass flow rate were found. Regions of instability were predicted by a linear stability analysis. The oscillations are caused by the following feedback circuit: boil up - level movement - void fraction of the discharging mixture - critical discharge rate - velocity of pressure decrease - boil up.
