This research conducted a study specially to systematically analyze combined recovery of exhaust gas and engine coolant and related influence mechanism, including a detailed theoretical study and an assistant experimental study. In this research, CO2-based transcritical Rankine cycle (CTRC) was used for fully combining the wastes heats. The main objective of theoretical research was to search a...

This paper focuses on the use of CO2 + SO2 binary mixture as innovative working fluid for closed transcritical power cycles with a minimum temperature above 50 °C. Starting from literature review available experimental data mixture, PC-SAFT EoS is identified suitable model to characterize behavior. Once proper thermodynamic selected this comparison between cycle and sCO2 proposed various plant ...

Nowadays supercritical CO2 cycles are considered as a promising alternative to the traditional steam cycle for power block in CSP plants with aim of enhancing system efficiency and reducing costs. This work deals experimental characterisation blend working fluid transcritical cycle: addition C6F6 dopant increases critical temperature allowing condensing hot environment ambient higher than 40 °C...

Concerning the use of HFCs as substitutes for CFCs and HCFCs a major concern in applications with remarkable leakages of refrigerant is its contribution to global warming. Therefore, the attention has been drawn to the use of natural working fluids, like carbon dioxide, hydrocarbons, water and air. Air had been already used in the range of air conditioning technology. Air as refrigerants is sta...

We consider shallow-water flow past a broad bottom ridge, localized in the flow direction, using the framework of the forced Su–Gardner (SG) system of equations, with a primary focus on the transcritical regime when the Froude number of the oncoming flow is close to unity. These equations are an asymptotic long-wave approximation of the full Euler system, obtained without a simultaneous expansi...

An inventory study of the energy use in cold storage installations in The Netherlands showed that frozen storage and combined chilled storage and distribution are responsible for a substantial part of the energy consumption of the sector. Two reference complexes including a standard number of refrigerated rooms can represent these two categories of plants. These reference complexes are used to ...

We consider families of random dynamical systems induced by parametrized one dimensional stochastic diierential equations. We give necessary and suucient conditions on the invariant measures of the associated Markov semigroups which ensure a stochastic bifurcation. This leads to suucient conditions on drift and diiusion coeecients for a stochastic pitchfork and transcritical bifurcation of the ...
