An air pull-through vortex model was implemented in RELAP5/MOD3 to investigate air-entrainment from a draining tank. Surge tanks covered by an air bubble are vulnerable to the entrainment of air into the liquid. If such a system is connected to a pump the possibility of entrained air from draining resulting in cavitation and pump degradation is possible.
