Otto Cycle: Thermodynamic Processes, Efficiency and PV & TS Diagrams

The Otto cycle is an ideal thermodynamic cycle, which forms the basis of conversion of the chemical energy of fuel into useful mechanical work with a spark ignition internal combustion engine. Otto cycle was developed by the German Engineer, Nicolaus August Otto in the year 1876. It is …

Back Work Ratio in Brayton Cycle: Definition, Formula, Derivation and Significance

The Back Work Ratio is an important parameter of a Brayton Cycle, which is the fundamental thermodynamic cycle used in gas turbines and jet engines. Unlike the steam power plants that runs on Rankine Cycle, gas turbines require a substantial portion of turbine’s output to drive the compressor, …

Reverse Brayton Cycle (Bell–Coleman Cycle): Working Principle, COP and Applications

The Reverse Brayton cycle or Bell Coleman cycle is an air refrigeration system, which is reversed from the Brayton cycle for producing refrigeration and cooling effect. Instead of converting the heat into mechanical work, in reverse Brayton cycle, mechanical work is consumed to transfer heat from a low …
