Heat engine efficiency depends on the maximum and minimum temperature of the cycle: Carnot states that the efficiency of the heat engine is independent of the type of fluid and only depends upon the maximum and minimum temperatures during the cycle. Thus the efficiency of the heat engine is hig...
. This is the maximum thermal efficiency a heat engine operating between two reservoirs at TH and TL can have. Because all processes in Carnot cycle is reversible, the cycle can be reversed. In this case we obtain reversed Carnot cycle. A refrigerator or heat pump operating on reversed ...
A Carnot cycle operating as a heat engine. The area ABCDA enclosed by these process paths represents the net work performed by the engine in one cycle. Then, using Equation (10-22), we find the efficiency of the Carnot cycle to be (10-24)∈C=1−|Q2Q1| An important proposition, ...
It depends on the numerator heating pump of converse Carnot cycle, cold warm manner and devicePURPOSE: To provide a method for cooling or heating with a molecular heat pump of a low-cost reversed Carnot cycle by eliminating consideration for elevated technique for generating a ferromagnetic field ...
It is noteworthy that when the efficiency of the Otto cycle exceeds the Carnot cycle, the system operates as a quantum refrigerator. As the number of photons increa- ses, Fig. 5b reveals that the QOM exhibits efficiency at lower x values, while the QCM demonstrates performance at a ...
The endoreversible hypothesis ∆SThw = −∆STcw gives the following constriction upon the contact times ratio tc th = σhc ac ah τ1−k 1 − ah−k ack − 1 , (26) where σhc ≡σh/σc. Since there is no heat leak, the efficiency of the internal Carnot cycle is the...
