In combustion, Clarke–Riley diffusion flame is a diffusion flame that develops inside a naturally convected boundary layer on a hot fuel surface with quiescent oxidizer environment, first studied and experimentally verified by John Frederick Clarke and Norman Riley in 1976.Clarke, J. F., & Riley, N. (1976). Free convection and the burning of a horizontal fuel surface. Journal of Fluid Mechanics, 74(3), 415-431. This problem is an extension of Emmons problem.
