Diesel Cycle Ideal vs Real Operation Analysis

In this course material, the open, simple Diesel Cycle used for stationary power generation is considered.

The Diesel Cycle thermal efficiency is presented only for the air as the working fluid.  The thermal efficiency derivation is presented with a simple mathematical approach.  The Diesel Cycle is presented in the p - V and T - s diagrams and its major performance trends (thermal efficiency and power output) are plotted in a few figures as a function of compression and cut off ratio values, combustor outlet temperature, some fixed cylinder geometry and both isentropic compression and expansion efficiency.  It should be noted that this course material does not deal with costs (capital, operational or maintenance).

His over 35 years engineering experience includes performing analytical modeling and computer modeling of physical properties, power cycles, power cycle components/processes and compressible flow.  Also, conducting conceptual design, analysis and evaluation of energy conversion systems for basic and simple power and propulsion cycles.
