N2 - The study of steam mass flow in a Curved Converging Diverging Nozzle has been analyzed using analytic and CFD modeling. The objective of this work is to get the comparison between the results of flow properties and characteristics from solution using thermodynamics analysis and turbulent model simulation. Using the post analysis of CFD simulation by integrating of the velocity at a cross flow section and the calculation supersonic flowing in the gradual area by EES® model, would be used to get the mass flow of steam, The simulation results give the good acceptance with the bias less than 7% compared to analytical. Saturated steam with stagnation pressure 200 kPa. and downstream area 71 cm2 with throat area 16 cm2, analytically and computationally could achieve the Ma about 3. At chocked condition, the maximum mass flow has the magnitude less than 0.016 kg/s, with the critical properties are 109.1 kPa; 341.9 °K; and 0.4092 kg.m3. The calculated mass flow has the magnitude 1.55 kg/s, meanwhile from simulation gives the mass flux magnitude 1.22 kg/s.
