Abstract
In performing synthesis or analysis of the combustion process in spark-ignition engines by digital computer, it is necessary to know the enflamed volume, the flame front area, and the area of the chamber surface in contact with the enflamed material, as functions of flame travel distance. This Note examines the case of spherical flame propagation in a disc-shaped chamber, with origin at any point on one of the flat surfaces. An ‘exact’ method of computation is outlined, and a simple approximate procedure, giving high accurary for this particular case, is described.
