— Radial inflow steam turbine technology is limited to turbocharger, waste heat recovery, gas turbine, solar,thermal, nuclear and geothermal power plant application up to 2-3 MW. The radial turbines are cost effective solutionfor power generation as compared to axial turbines. To understand whether radial turbine design can be scaled up to inthe range of 20-30 MW, effort were made to carry out the design of 20-30 MW radial turbine using in-house developedprogram and commercial codes. Meridional flow path design is developed for 11 number of stages with stage loadingcoefficient in the range of 0.982-1.12 keeping in view to minimize the number of stages. The overall flow path length isachieved is approximately 2500 mm with total to static efficiency of 81%. A uniform tip clearance of 1 mm is assumed forthe estimation of efficiency. MST and CFD analysis is carried out to understand the flow and loss behavior within thevarious components in the turbine. The flow path is modified iteratively to improve the flow behavior and associatedlosses in the rotating as well as stationary passage. Further, to understand the mechanical behavior of the rotor, FiniteElement Analysis (FEA) of the rotor parts is carried out.
