- During the operation of the low-pressure steam turbine, condensation phenomenon is observed in stationary and rotating blade cascade. In this paper Numerical method was employed to simulate steam flow in linear blade cascade in order to study the surface pressure distribution and flow field characteristics. Initially, 2D Dykas cascade results validated with the k-ω SST viscous turbulence model for vapour liquid mixture, then the 3D cascade model was simulated with IAPWS IF-97 model. From the comparative study of both models, IAPWS IF-97 model wasquite easy to implementduring the simulation which gives more accurate blade surface pressure distribution according to standards. Also, it helps in the design process of steam turbine blades https://journalnx.com/journal-article/20150538
