Design of micro radial turboexpanders for ORC power cycles: From 0D to 3D

The design of the rotor was reconsidered as a consequence of the 3D CFD approach. Finally, the comparison between the 0D and 3D results was carried out, showing a good agreement between the two approaches and, thus, verifying the reliability of the combined 0D-3D design tool for micro-size turboexpanders of ORCs.
