Abstract
Many industrial applications use flame impingement to obtain high heat-transfer rates. An analytical expression for the convective

part of the heat transfer of a flame jet to a plate is derived. Therefore, the flame jet is approximated by a hot inert jet. In contradiction

with existing convective heat-transfer relations, our analytical solution is applicable not only for large distances between the jet and the

plate, but also for close spacings. Multiplying the convective heat transfer by a factor which takes chemical recombination in the cold

boundary layer into account, results in an expression for the heat flux from a flame jet to the hot spot of a heated plate. Numerical and
