Solar Rankine Cycle System Using Scroll Expander

Experimental Testing of an Organic Rankine Cycle with Scroll-type Expander

An organic Rankine cycle (ORC) is a power cycle employing an organic working fluid. The term ORC is also applied generally to any Rankine cycle with a low-grade heat source (80° – 300 o C). Because ORC are often employed in small-scale applications, use of positive displacement equipment is favored over the centrifugal units used in large-scale power plants. A key feature of a positive displace...

Numerical Simulation of a Scroll Expander for Use in a Rankine Cycle

Optimal Control of Exhaust Recovery Generator System with Scroll Expander

A scroll expander exhaust recovery system with the battery is proposed to improve exhaust recovery efficiency. Based on the exhaust flow, storage pressure and the battery current, expander supply pressure was optimized with the loss model based on the expansion and generator loss. And then the supply pressure controller was designed to track the optimized supply pressure reference using the inp...

Experimental and Thermoeconomic Analysis of Small-Scale Solar Organic Rankine Cycle (SORC) System

A small-scale solar organic Rankine cycle (ORC) is a promising renewable energy-driven power generation technology that can be used in the rural areas of developing countries. A prototype was developed and tested for its performance characteristics under a range of solar source temperatures. The solar ORC system power output was calculated based on the thermal and solar collector efficiency. Th...

A Review on Solar Collector and Solar Organic Rankine Cycle (ORC) Systems

Solar-driven organic Rankine cycle (ORC) has been drawing increasing attention due to its high potential in energy conversion efficiency. The two core components of thermal application systems of solar energy are solar collectors and thermal energy storage systems, and many studies have been published. ORC also has attracted much attention in recent years due to its potential in reducing consum...
