Abstract

Abstract

Based on 170 density wave oscillation experimental data from parallel round tube and narrow rectangular channel,the experiment method,identification method of oscillation and analysis method of experimental data have be uniformed,and the oscillation boundary of round tube and narrow rectangular channel have be analyzed.The investigation results show that the oscillation boundary is not affected by the channel section forms with identical equivalent diameter with pressure 1.0~19.2 MPa,mass flux 101.9~1200.0 kg.m^-2.s^-1 and inlet sub cooling 18.0~85.2℃.
