WebIn recent decades, the approach known as Finite-Time Thermodynamics has provided a fruitful theoretical framework for the optimization of heat engines operating between a heat source (at temperature ) and a heat sink (at temperature ). The aim of this paper is to propose a more complete approach based on the association of Finite-Time … WebApr 23, 2024 · In an air - standard Carnot cycle, heat is transferred to the working fluid at 1150 K, and heat is rejected at 300 K. The heat transfer to the working fluid at 1150 K is 120 kj/kg. The maximum pressure in the cycle P, is 16.5 MPa. Assuming constant specific heat of air, determine the cycle efficiency and pressure at different points of cycle.
WebThe Carnot cycle consists of the following four processes: A reversible isothermal gas expansion process. In this process, the ideal gas in the system absorbs qi n amount heat from a heat source at a high temperature Th, expands and does work on surroundings. A reversible adiabatic gas expansion process. WebIn this process, there is no transfer of heat, the temperature of the substance falls to T 2 and it does some external work W 2 given by, W 2 = ∫ V 2 V 3 P. d V = K ∫ V 2 V 3 d V V γ Because, during adiabatic process, ( P V γ = c o n s tan t = K) = K V 3 1 − γ − P 2 V 2 1 − γ = P 3 V 3 − P 2 V 2 1 − λ ( P 2 V 2 γ = P 3 V 3 γ = K)
In a Carnot cycle, a system or engine transfers energy in the form of heat between two thermal reservoirs at temperatures and (referred to as the hot and cold reservoirs, respectively), and a part of this transferred energy is converted to the work done by the system. See more A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s.
