Lenoir Cycle
The Lenoir cycle is an idealized thermodynamic cycle often used to model a pulse jet engine. Lenoir Cycle consists of a constant volume heat addition, Isentropic expansion, and the constant pressure heat rejection processes. There is no compression process for the working fluid.
Due to the absence of the compression process, it will results in less thermal efficiency than the other Air-Standard Cycles such as the Otto Cycle, Diesel Cycle, Dual Cycle.
How to Calculate Thermal Efficiency of Lenoir Cycle?
Thermal Efficiency of Lenoir Cycle calculator uses Thermal Efficiency of Lenoir Cycle = 100*(1-Heat Capacity Ratio*((Pressure Ratio^(1/Heat Capacity Ratio)-1)/(Pressure Ratio-1))) to calculate the Thermal Efficiency of Lenoir Cycle, The Thermal Efficiency of Lenoir Cycle formula is defined as the fraction of heat converted into useful work in the engine following Lenoir cycle. It depends upon the pressure ratio as well as the ratio of specific heats, i.e. adiabatic index. Thermal Efficiency of Lenoir Cycle is denoted by ηlenoir symbol.
