Title: MODELING THE BURNING OF COMPLICATED OBJECTS USING LAGRANGIAN PARTICLES
Published: July 04, 2010
Abstract: A methodology is described for representing complicated objects within a computational fluid dynamics model. These objects are typically collections of similar items that are too small to define on the numerical grid that is used to solve the governing flow equations. Examples include vegetation like leaves and grasses, electrical cables, office clutter, and wooden cribs used in fire experiments. The basic idea is to use Lagrangian particles that are not tied to the numerical grid as a means of representing the small items. The particles can take on simple shapes like spheres, cylinders or plates, and detailed material properties can be assigned to them. A basic outline of the method and some examples are presented.
