WebIrreversible adiabatic expansion For an irreversible adiabatic expansion in which some work is performed, the work performed is less in magnitude than that in the reversible process because the external pressure is less than the pressure of the gas by a finite amount. WebFor example, Joule expansion is irreversible because initially the system is not uniform. Initially, there is part of the system with gas in it, and part of the system with no gas. For dissipation to occur, there needs to be such a non uniformity. ... Irreversible adiabatic process: If the cylinder is a perfect insulator, the initial top-left ...
WebNov 16, 2024 · If the expansion is irreversible and adiabatic, the gas does less work, looses less internal energy and so there is entropy increase as the cooling is now not as large as when expansion is adiabatic and reversible, and so the two process, entropy increase due to expansion and decrease due cooling no longer match. Share Improve this answer Follow WebDec 3, 2024 · Suppose an irreversible adiabatic expansion process and a reversible adiabatic expansion process are starting from the same initial state, say, P1V1. Now, let both of these processes have equal pressure in their final state.
WebFeb 17, 2015 · The irreversibility comes in because the expansion will be very rapid, and the gas will experience viscous dissipation of mechanical energy to heat. This is essentially the same thing that happens in a spring-mass-damper system, with the damper being analogous to the viscous dissipation in the gas. WebThis paper aims to contribute to a better understanding of the concepts of a "reversible process" and "entropy". For this purpose, an adiabatic irreversible expansion or compression is analysed, by considering that an ideal gas is expanded (compressed), from an initial pressure P[subscript i] to a final pressure P[subscript f], by being placed in contact with a …
WebIn this paper, a recompression S-CO2 Brayton cycle model that considers the finite-temperature difference heat transfer between the heat source and the working fluid, irreversible compression, expansion, and other irreversibility is established. First, the ecological function is analyzed. Then the mass flow rate, pressure ratio, diversion …
