ANALYSIS OF LAMINAR FLAME DEVELOPMENT IN A SPHERICAL VESSEL.

Laminar flame development in a spherical vessel has been simulated accurately and solutions have been compared with the ones by the other investigators. The effects of differences in estimating physical values of gases on the calculated results were examined and the incorrectnesses in the analyses which have been revealed until now are pointed out. Accurate simulations give higher convergence ability in deriving the results compared with those by the concepts of isobaric combustion for which heat exchanges are introduced tacitly. It is proved that the relations between mass burnt ratio and pressure increment ratio can be rearranged into a curve irrespective of the differences in fuels and initial pressures.
