Organic Rankine Cycle with Flooded Expansion and Internal Regeneration
- Summary
- Researchers at Purdue University have developed an enhanced ORC-type heat engine that provides comparable benefits to traditional cycle enhancements at a reduced cost and complexity. These enhancements reduce the heat input to the system and increase its efficiency. It is an economical way to extract more work from waste heat streams or geothermal temperature sources.

- *Abstract
-
- *Background
- An Organic Rankine cycle (ORC) is often used to recover waste heat, which are typically small-scale applications where thermal efficiency is low and the benefits of traditional cycle enhancements, such as reheat stages or feedwater heaters, do not typically outweigh the cost of implementing. An ORC with flooded expansion and internal heat regeneration is an alternative method of enhancement.
