Supercritical CO2 Brayton-based cycles are a promising technology for concentrated solar power plants. Their high efficiency can be improved by using mixtures as working fluid instead of pure CO2. This work studies 3 cycle topologies: simple recompression (RCC), with main compressor intercooling (RCMCI) and partial cooling (PCRC), across range regenerator conductance (UA), turbine inlet temperatures. Each topology is simulated different fluids: CO2, CO2–NH3, CO2–SO2, CO2–COS CO2–H2S. The...
This paper presents an abbreviated method for estimating exergy destruction in a heat exchanger, requiring only black-box data of the exchanger’s inputs and outputs, eliminating part mathematical difficulties associated with calculations. A well-known model temperature distributions exchanger is adapted this case, used to distinguish between contributions three major causes total exergetic loss: transfer, fluid friction energy dissipation surroundings. provides insight into relative...
The optimum pressure ratio for the stages of a multistage compression process is calculated with well known formula that assigns an equal all stages, based on hypotheses isentropic efficiencies are also equal. Although derivation this two relatively easy to find, it more difficult find any number and examples found in literature employ complex mathematical methods. case when have different only treated numerically. Here, step by general stage carried out using Lagrange multipliers. A main...
Although CO 2 as refrigerant is well known for having the lowest global warming potential (GWP), and commercial domestic heat pump water heater systems exist, its long expected wide spread use has not fully unfolded. Indeed, poses some technological difficulties with respect to conventional refrigerants, but currently, these have been largely overcome. Numerous studies show that heaters can improve coefficient of performance (COP) ones in given conditions. In this study, performances...
The problem of the high carbon dioxide emissions linked to power generation makes necessary active research on use biofuels in gas turbine systems as a promising alternative fossil fuels. Gasification biomass waste is particularly interest obtaining fuel be run turbines, it an efficient biomass-to-biofuel conversion process, and integration into combined cycle plant leads performance with regard energetic efficiency. goal this study was carry out energetic, exergetic environmental analysis...
The utilisation of biofuels in gas turbines is a promising alternative to fossil fuels for power generation. It would lead significant reduction CO2 emissions using an existing combustion technology, although considerable changes appear be required and further technological development necessary. goal this work conduct energy exergy analyses the behaviour fired with biogas, ethanol synthesis (bio-syngas), compared natural gas. global transformation process (i.e., from biomass electricity)...
In this work, an evaluation and quantification of the impact using mixtures based on supercritical carbon dioxide “s-CO2” (s-CO2/COS, s-CO2/H2S, s-CO2/NH3, s-CO2/SO2) are made as a working fluid in simple complex recompression Brayton s-CO2 power cycle configurations that have pressure drops their components. These cycles coupled with solar thermal plant parabolic-trough collector (PTC) technology. The methodology used calculation performance is to establish values heat recuperator total...

The proposal outlined in detects lane by means...
The functional capabilities that consciousness seems to provide biological systems can supply valuable principles in the design of more autonomous and robust technical systems. These concepts keep a notable similarity those underlying notion operating system software engineering, which allows us specialize computer metaphor for mind into consciousness. In this article, departing from these ideas model-based theoretical framework cognition, we present an architectural proposal machine...

Three alternatives for integrating a solar field with the bottoming cycle of combined plant are modeled: parabolic troughs oil at intermediate and low pressures Fresnel linear collectors pressure. It is assumed that will always operate nominal conditions, using post-combustion during hours no resource. A thermoeconomic study operation throughout year has been carried out. The energy exergy efficiencies working in fuel only hybrid modes compared. obtained very similar; slightly better mode....
