Direct numerical simulation of a simple reaction between two scalar in a plane turbulent wall jet has been performed. In addition to mean and fluctuations also the higher order statistics and the probability density functions of the reacting scalars have been examined. The probability density functions will shed light on the passive and reacting scalars behavior close to the wall and also to the near-wall characteristics of the reaction.
