Basic configurations- Matching with nozzle exit velocity- Tip diameter by the rotational speed- Number of blades- Decide turbine efficiency- Optimum hub diameter (flow quality is changed within the passage) etc.

A turbo expander is installed in the expansion process instead of expansion V/V. It recovered 0.37kJ/kg on the 9.25RT experimental utility.Efficiency increases according to the pressure ratioEfficiency drops linearly 3.7% between shroud and un-shroud rotor Experimental study is very important exact manufacturing of test systemSpecially, micro rotating machine required manufacturing quality is 0.001mm
