A Method of Calculating a Time-Varying Volume of Combustion Products in the Cylindrical Chamber

open access: yesМеханика машин, механизмов и материалов, 2008
A method of calculating a volume of combustion products when a flame spreads in the closed cylindrical chamber is developed, assuming that the front is spherical for two positions of an ignition source: at the end (central ignition) and cylindrical (side
