In an adiabatic process in which only one of the variables is altered, the system can only return to the initial state if an additional variable of state is also reversed. If the work done on the gas during compression is the same as the work done by the gas during expansion, the ...
of just the gas inside the cylinder and assuming this system is insulated and the process quasistatic, pressure at the gas-piston interface should be equal (P_ interface) and the system only sees P_ interface applying work onto it during compressing and applying P_ interface during expansion....
Are the Gibbs and Helmholtz free energy both equal to 0 when the process is irreversible? such as a sudden expansion or compression? Logged mjc123 Chemist Sr. Member Posts: 2075 Mole Snacks: +302/-12 Re: Free energy in irreversible processes ...
It is assumed that temperatures of two heat reservoirs are TH and TL, heat conductances of two HEXs are UH and UL, and working substance is an ideal gas and has heat capacity rate Cwf, respectively. Download: Download high-res image (72KB) Download: Download full-size image Fig. 1. ...
In summary the objective of this work is to present a novel and unified theoretical model of a multi-step regenerative closed Brayton cycle that allows the consideration of an arbitrary number of intercooled compression steps and reheated expansion steps. We take into account the main irreversibilit...
This is indeed the case for the free expansion of initially confined particles whose accessible phase space is increased by removing the partitioning barrier. In this work, we explore the fact that in systems driven through second-order phase transitions, both the abso- lute irreversibility and ...

Figure 5a illustrates a closed system in which an ideal gas undergoes an adiabatic expansion process with friction. The First Law of Thermodynamics requires that the increase in internal energy of the gas equals the energy decrease of its surroundings. It is assumed that dx is the piston ...
The cycle consists of an irreversible adiabatic compression process (process 1–2), two isobaric heat absorption processes (processes 2–3 and 3–4), an IHP (process 4–5), an irreversible adiabatic expansion process (process 5–6) and two isobaric exothermic processes (processes 6–7 and 7...
