Thermodynamic performance analysis of supercritical carbon dioxide Brayton cycle

نویسندگان

چکیده

The supercritical CO2 is used as working fluid for power system cycle. This paper presents thermodynamic performance analysis results on Brayton Based the assumptions of relevant initial parameters, mathematical models compressor, turbine, recuperator and heater are constructed, thermal efficiency regenerative cycle recompression calculated analyzed. reveal that higher than simple effects inlet temperature, pressure main compressor turbine studied, influencing mechanism explained. show decreases with increase temperature compressor. There exists an optimum in to maximize efficiency. increases turbine. When exceeds 600?, can reach more 50%.

Thermodynamic Analysis of an Irreversible Maisotsenko Reciprocating Brayton Cycle

An irreversible Maisotsenko reciprocating Brayton cycle (MRBC) model is established using the finite time thermodynamic (FTT) theory and taking the heat transfer loss (HTL), piston friction loss (PFL), and internal irreversible losses (IILs) into consideration in this paper. A calculation flowchart of the power output (P) and efficiency (η) of the cycle is provided, and the effects of the mass ...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

Reactions in supercritical carbon dioxide

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...
