Abstract

Abstract

Serious steam condensation induced water hammer（CIWH） phenomenon would occure when the steam directly contacts with the water during the residual heat removal process for nuclear reactors.In this paper,CIWH phenomenon was investigated experimentally in a horizontal pipe.Firstly,it was found that CIWH would cause a high pressure peak,and there periodically appeared decaying pressure peaks after CIWH event.Besides,the existence of pressure difference for different positions promoted CIWH event by analyzing pressure fluctuation of different axial positions.Finally,multiple CIWH events occurred during 120 s,but pressure fluctuation intensity had a high randomness.The maximum value of pressure fluctuation intensity increased with steam mass flux increasing with a maximum value of 10 MPa.
