Thermodynamics

Air-fuel (AF) ratio

Physics; Thermodynamics

A variable used in the analysis of combustion processes to quantify the amounts of fuel and air for optimal performance. It is usually expressed on a mass basis and is defined as the ratio of the ...

Chemically correct amount of air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

Theoretical amount of air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

Stoichiometric air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

The pressure of a vapour in thermodynamic equilibrium with its condensed phases in a closed system such water vapour in atmospheric air. All liquids have a tendency to evaporate, and some solids can ...

Conservation of mass principle

Physics; Thermodynamics

The fundamental principle used to balance chemical reaction equations. It states that the total mass of each element is conserved during a chemical reaction. The total mass of each element on the ...

Isentropic stagnation state

Physics; Thermodynamics

The stagnation state in which the stagnation process is reversible as well as adiabatic or isentropic. The entropy of a fluid remains constant during an isentropic stagnation process.
