| 10. | Abstract : a numerical model and experiments over pmma are used to evaluate the main assumptions used in the theoretical description of a diffusion flame established in a natural boundary layer . flow characteristics ( 2 - d boundary layer ) and surface thermal balance are identified as the critical assumptions to be evaluated . comparison of experiments , numerical results , and theoretical model serve to validate the assumptions leading to the definition of a mass transfer number but establish the need to model all three - dimensional features of the flow
