This paper presents a dynamic propagation view that the continuity wave and dynamic wave acting on each other results in the non linear solution under certain flow conditions. Based on the drift flux model and empiric formula, hyperbolic equation of one dimensional gas liquid two phase flow is deduced, wave theory approach is performed in detail by using characteristic curve method. The numerical analysis shows flow pattern transition location propagates downstream ward for lower void fraction while it moves upstream ward for higher void fraction. Flow pattern transition would not occur for very high void fraction. The calculations show that the inception of flow pattern transition is at the void fraction of 0.27 and the flow pattern transition stops at the void fraction of 0.58, which is in good agreement with experimental results in literatures.
