An experimental investigation of oscillatory flow instabilities was conducted in a two-phase flow system, which has a negative slope region of the pressure drop characteristics and compressible volume in each gas and liquid supply line. The characteristics of relaxation oscillation and quasi-harmonic oscillation are presented.
