Abstract
Multi-vane expanders possess many advantages, over turbines and other positive-displacement machines, as prime movers for low-grade energy engines of small power outputs. It has been found that the performances of such expanders can be improved considerably by optimizing their design and operating variables. For an organic Rankine-cycle engine, utilizing low-temperature heat as the input, a multi-vane expander with isentropic efficiencies exceeding 73 per cent at rotational speeds up to 3000 r/min was designed, built and demonstrated.
