CFD Analysis to Envisage the Fluid Flow Inside a Turboexpander Operating at Cryogenic Temperature

The one-dimensional design methodology of radial turbine blade profile has a substantial role in the advancement of an efficient liquefaction cycle (cryogenic fluids) because of growing demand in research and various industrial applications. The main part of the current study is to obtain an optimum design of radial turboexpander. The CFD analysis of a turboexpander is carried out to characterize the flow filed inside it. The initial blade profile is generated using ANSYS Blade-Gen which is further modified based on CFD analysis. The pressure, temperature, velocity, static enthalpy and entropy at various cross sections are reported.
