- •
A new single screw expander was developed and integrated into an Organic Rankine Cycle system.
- •
The under expansion losses seem to be eliminated by the new structure of the single screw expander.
- •
The maximum shaft efficiency and isentropic efficiency were 56% and 73%, respectively.
- •
The maximum efficiency of the circulation pump was 31%.
- •
The efficiency of the experimental Organic Rankine Cycle system achieved 7.98%.
