Advanced Otto Cycle and Combustion Analysis

Description

This engineering course presents the open, simple Otto Cycle — the ideal cycle for a simple gasoline engine — as used for stationary power generation, together with a detailed combustion analysis. For the Otto Cycle, only air is used as the working fluid.

What this course covers:

• Thermal efficiency derivation for the Otto Cycle using a simple mathematical approach, with p-V and T-s diagrams
• Power cycle performance trends — thermal efficiency, specific power output, power output, combustion products composition (weight and mole basis), specific fuel consumption and stoichiometry — plotted against compression ratio and combustion temperature
• Combustion of six fuels (carbon, hydrogen, sulfur, coal, oil and gas) with air and oxygen-enriched air as the oxidant at varying stoichiometry (stoichiometry => 1) and oxidant inlet temperatures
• Combustion performance derived from the specific enthalpy values of reactants and products as a function of temperature, with products composition given in tabular and plotted form
• Flame temperature, oxidant-to-fuel ratio and fuel higher heating value (HHV) presented in tables and figures

The output data and plots let you determine the major combustion performance laws and trends. Note that this material does not address capital, operational or maintenance costs.
