Course Learning Outcomes:

Upon completion of this course, students will be able to

Objective 1

1.1 understand the concepts of internal energy, enthalpy and equilibrium constants.

1.2 calculate the composition of a perfect gas mixture at equilibrium and its adiabatic flame temperature.

1.3 calculate concentration time-histories in elementary kinetic mechanisms.

1.4 understand basic molecular collision theory and to be able to identify different types of reaction classes and effects of pressure and temperature on product distributions.

Objective 2

2.1 understand the derivation of equations for mass, momentum, energy, and species conservation for laminar and diffusion flames.

2.2 identify key issues relating to the formation and destruction of primary pollutants such as oxides of carbon and nitrogen and compounds that present immediate health and environmental problems such as particulates.

2.3 show how the relative importance of diffusion and thermal conductivity in laminar flames affect the oxidation of fuels.

2.4 derive the conservation equations for the oxidation of single particles droplets. Identify limiting cases and the role of sprays in the case of liquids.

2.5 identify and understand the physics behind dimensionless groups including the Prandtl, Schmidt, and Damköhler numbers.

2.6 understand the difference between the following four types of combustion processes: laminar premixed flames, turbulent premixed flames, homogeneous reaction (knock) and non-premixed spray or droplet flames
