Classification of Thermodynamic Cycles! Thermodynamic Cycle # I. Carnot Cycle: It consists of two isothermal processes and two isentropic processes. This cycle is represented on temperature-entropy and pressure-volume diagrams as shown in fig. 2-34. Consider one kg of air at temperature T1 as the working fluid in the engine cylinder. Let point 1 (fig. 2-34) represent the state of the [...]
Compilation of lecture notes on ‘Improved Rankine Cycles’ in thermodynamics for engineering students. Lecture Note # 1. Carnot and Rankine Cycle: Carnot cycle is the most efficient thermodynamic cycle for all the heat engines utilising the heat energy and producing mechanical energy. We have also observed that there are limitations for the use of this cycle in practice. The ideal [...]
Here is a list of seven major air standard cycles. 1. Otto – Cycle (Constant Volume Cycle): To avoid high values of pressures and compression ratios, a practical cycle was introduced by a German Scientist Dr. A .N. Otto in 1876 and it was successfully applied for the working of petrol and gas engines. This cycle consists of two isentropic [...]
