Based on the study of variable operating conditions and experimental verification of a small-scale ORC with a scroll expander
As a fundamental component of the organic Rankine cycle(ORC),the scroll expander's operating characteristics critically influence the ORC's overall performance.Initially,we establish a three-dimensional transient simulation model of the scroll expander.This allows us to systematically analyze the effects of various operating conditions on aspects such as suction pressure,exhaust pressure,rotational speed,and the output power and isentropic efficiency of the scroll expander,using numerical simulation.Following this,we study the effect of different operating conditions on the transient performance and mechanical properties of the scroll expander,and achieve a more comprehensive understanding of the mechanisms involved.Ultimately,we verify the accuracy of our numerical model using a laboratory-built test bench of the ORC low-temperature waste heat oil-free power generation system.The close correlation between the experimental results and numerical simulation outcomes authenticates the reliability and applicability of our numerical simulation method.In conclusion,this research's findings offer significant referential value for the design and optimization of the scroll expander.
