Experimental studies on density wave oscillation instability of two-phase flow in parallel ver-tical rifled tubes were conducted on two-phase high pressure test loops. The main characteristics of density wave oscillation instability were perceived. In the range of test parameters, the effects of heat flux, pressure, mass velocity, inlet sub-cooling, asymmetric heat flux on the density wave oscillation instability of two-phase were explored and analyzed. Based on the test result and using the homogeneous model, the threshold rela-tional expressions of density wave oscillation instability were obtained.
