Description

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).

In this course material, the student gets familiar with the Diesel Cycle, its components, p - V and T - s diagrams, ideal and operation and major performance trends.
