IGNITION MODELING WITH GRID ADAPTATION
Western States Section, Combustion Institute (Paper)
Date of Presentation
We have developed a computational model that can predict the detailed chemical behavior of ignition in fuel-air mixtures. The physical problem we have chosen as an illustration here is one in which thermal energy is added at the center of an enclosed chamber filled with premixed fuel and oxidizer. We solve one-dimensional conservation equations for compressible flow in planar, cylindrical, or spherical coordinates and employ a grid adaptation scheme to follow dynamically the motion of thin fronts. The model computes the transient development of a self-propagating deflagration, if it occurs, and follows the fluid dynamic behavior of pressure waves that are generated by the fluid expansion.
