Accurate prediction of gas-liquid two-phase flow with rapid transition is of significant importance to design various industrial plants and to evaluate their safety. However, the one-dimensional two-fluid model that is often used for these purposes requires constitutive equations and most of them are based on the experimental data of two-phase flow in steady state. Thus, to confirm the applicability of the one-dimensional two-fluid model to the transient state, several two-phase parameters during rapid transition were measured and they were compared with the numerical solution of the one-dimensional two-fluid model. As a result, the agreement between the numerical solutions and the experimental data was not deteriorated during the transition. This would imply that the one-dimensional two-fluid model is applicable to the transient two-phase flow within the present experimental conditions.
