A research was carried out using a simplified hydraulic model in which the void fraction was calculated by iteration; according to the computing result of both adiabatic and uniform heated two-phase pipelines, the comparison was given, and the details showed that theoretical analysis was well agreed with experimental results and provided a refer- ence for engineering application.
