“…Less numerous than overall ORC studies are efforts focused on specific components. Among expander studies, publications examine turbines [126,186,209], scroll expanders [174,175,228,272], screw expanders [128,212,232], piston expanders [198,212,273],…”

“…Another US DOE update [174] follows the completion of a government-funded study, in this case based on the work of Dieckmann [175] targeting the use of scroll expanders for industrial WHR. The expander in the study aims to be compact and cost-effective while also offering simplicity and efficiency, a set of characteristics admirably balanced by the manufacturer (TIAX).…”

The last decade (2013–2023) was the most prolific period of organic Rankine cycle (ORC) research in history in terms of both publications and citations. This article provides a detailed review of the broad and voluminous collection of recent internal combustion engine (ICE) waste heat recovery (WHR) studies, serving as a necessary follow-on to the author’s 2013 review. Research efforts have targeted diverse applications (e.g., vehicular, stationary, and building-based), and it spans the full gamut of engine sizes and fuels. Furthermore, cycle configurations extend far beyond basic ORC and regenerative ORC, particularly with supercritical, trilateral, and multi-loop ORCs. Significant attention has been garnered by fourth-generation refrigerants like HFOs (hydrofluoroolefins), HFEs (hydrofluoroethers), natural refrigerants, and zeotropic mixtures, as research has migrated away from the popular HFC-245fa (hydrofluorocarbon). Performance-wise, the period was marked by a growing recognition of the diminished performance of physical systems under dynamic source conditions, especially compared to steady-state simulations. Through advancements in system control, especially using improved model predictive controllers, dynamics-based losses have been significantly reduced. Regarding practically minded investigations, research efforts have ameliorated working fluid flammability risks, limited thermal degradation, and pursued cost savings. State-of-the-art system designs and operational targets have emerged through increasingly sophisticated optimization efforts, with some studies leveraging “big data” and artificial intelligence. Major programs like SuperTruck II have further established the ongoing challenges of simultaneously meeting cost, size, and performance goals; however, off-the-shelf organic Rankine cycle systems are available today for engine waste heat recovery, signaling initial market penetration. Continuing forward, next-generation engines can be designed specifically as topping cycles for an organic Rankine (bottoming) cycle, with both power sources integrated into advanced hybrid drivetrains.

“…Scroll-type expanders are widely applicable as secondary devices in various thermodynamic cycles. Scroll systems, use the energy available from sources like exhaust gases of internal combustion engines (YijiLu, 2017), biomass (Moro & Pinamonti, 2008), waste heat from industry (ClaudioCampana, 2019), (DOE:US, 2017), thermal energy from solar panels (Dieckmann, 2017), and heat energy from geothermal sources (Lu, 2015). From the review, it can be determined that scroll-type expanders are well-suited for the generation of low-grade power.…”

additional advantages when it comes to replacing equipment in automobiles for smooth, frictionless operation (Fatigati et al., 2022). They can also work in both dry and wet conditions, which is useful in heat-generating applications.The operation of the scroll machine is very simple and makes its simplicity a major factor in many industries. The other factors like compactness and durability are the added advantages of the scroll machine. These factors make it a viable choice as an expander in various industries including small-scale ORC systems (Fatigatib, 2020). The scroll expander was divided into three major categories like hermetic scroll-type expanders, semi-hermetic scroll-type expanders, and open scroll-type expander drive expanders were studied in the literature study done by Fatigatib (Fatigatib, 2020) in the year 2020. A review by Fatigatib (Fatigatib, 2020) , studied a small-scale ORC-based test bench. The working fluid considered in the study is R134a for debuting a hermetic scroll expander. The scroll-type expander used in the study is derived from a compressor and used three poles asynchronous engine for integrating the hermetic scroll-type expander developed. Literature ReviewScroll expander application in the automobile industry has been tested (Fatigati et al., 2022). In this research, the scroll expander's feasibility as a dual intake port is analyzed. Similarly, research on a large number of micro-to small-scale organic Rankine cycle (ORC) applications are Frontiers in Heat and Mass Transfer
