A turboexpander is a centrifugal or axial flow turbine through which a high pressure gas is expands toproduce work to drive compressor. Cryogenic turboexpanders are used in many applications, including ethylene plants,refineries, gas processing plants and air separation facilities. It is widely used as sources of refrigeration in industrialprocesses such as the extraction of ethane and natural gas liquids (NGLs) from natural gas, the liquefaction of gases(e.g. Oxygen, Nitrogen, Helium, Argon, Krypton) and other low temperature processes.The work presents here is computational fluid dynamics (CFD) analysis of high speed radial flow turboexpandercompressor wheel. This analysis done in Solidworks flow simulation software. This project work deal with two majorparts; first one is form existing compressor wheel model and data, find out efficiency of turboexpander and compare theoutput result with theoretical calculations. Second part is to modify profile of blades to increase the efficiency. Thisinvolves three dimensional analysis of flow through radial expansion turbine using nitrogen as flowing fluid, flowbehavior at inlet and outlet area of turboexpander, thermal properties of fluid like pressure, temperature, entropy,enthalpy at various stages of cryogenic turbine.
