Atkinson cycle is an ideal cycle for Otto engine exhausting to a gas turbine. In this cycle, the isentropic expansion 3-4 of an Otto cycle (1-2-3-4) is further allowed ..
The thermodynamic cycle Brayton cycle can be compared with the Otto cycle to deduce the following points: Comparison of Pressure-volume and Temperature-entropy diagrams ..
If an object with a higher temperature comes in contact with an object of lower temperature, it will transfer heat to the lower temperature object. The objects will ..
A thermodynamic process which does not fulfill conditions of a reversible process is termed irreversible processes. Irreversibilities are the reasons causing the process ..
The First law of thermodynamics states that energy is neither created nor destroyed. Thus the total energy of the universe is a constant. However, energy can certainly ..
The simple Rankine cycle is also a reversible cycle. Consider the idealized four-steady-state-process cycle in which state 1 is saturated liquid and state ..
