Review of Reservoir Damage Mechanisms Induced by Working Fluids and the Design Principles of Reservoir Protection Fluids: From Oil–Gas Reservoirs to Geothermal Reservoirs

Energies
Various working fluids are applied during geothermal reservoir development, and geothermal reservoir damage induced by contacts between working fluids and reservoir formations are inevitable.

Parametric Optimisation of an ORC in a Wood Chipboard Production Facility to Recover Waste Heat Produced from the Drying and Steam Production Process

Energies, 2019
The wastes in wood industries (waste chips) are commonly used as fuel for burners to produce steam and to use the remaining heat in the drying process.

Integrated computer-aided working-fluid design and thermoeconomic ORC system optimisation [PDF]

, 2017
The successful commercialisation of organic Rankine cycle (ORC) systems across a range of power outputs and heat-source temperatures demands step-changes in both improved thermodynamic performance and reduced investment costs.

Natural Working Fluids for Absorption Refrigeration

, 2022
European and global regulations on greenhouse gases are constantly evolving. Most of the fluorinated refrigerants currently used are close to be banned due to their high global warming potentials. Therefore new alternatives less harmful to the environment need to be developed.

Thermo-Economic Analysis of Zeotropic Mixtures and Pure Working Fluids in Organic Rankine Cycles for Waste Heat Recovery

Energies, 2016
We present a thermo-economic analysis of an Organic Rankine Cycle (ORC) for waste heat recovery. A case study for a heat source temperature of 150 °C and a subcritical, saturated cycle is performed.

A Working Fluid Assessment for a Biomass Organic Rankine Cycle under Different Conditions

Energies, 2022
Many thermal resources are not reasonably used in the chemical industry’s production process. To recover the waste heat from organic waste residue-calcium carbonate (CaCO3), which is added to inhibit hydrogen production, an organic Rankine cycle (ORC ...

π–π Conjugated Bonds Stacking/Scattering for Switchable Lubrication in Supramolecular Hydrogel

Advanced Science
Existing polymer materials often lack the ability to dynamically adjust lubrication in response to external stimuli. This gap in adaptable lubrication technology limits their application in advanced systems such as intelligent motion devices and soft ...

Working fluid selection of Organic Rankine Cycles

Energy Reports, 2020
Organic Rankine Cycles (ORCs) are identified as one of the best candidates to generate electricity from low-grade heat sources. ORCs operate on low temperatures and low pressures with comparative to conventional Rankine Cycles.

Study on the Influence of Working-Fluid’s Thermophysical Properties on the Stirring-Heating

Energies, 2022
The thermophysical properties of a working-fluid play an important role in the process of stirring-heating. The heating process of stirring is accompanied by two processes: the friction between the solid mechanism and the working-fluid and the viscous ...
