The OH profiles change along with the increase of the distance from the channel
inlet.Concentration maximum is shifted into the area of the oxidizer in relation to the
flame, and its level is much lower than in the laminar flame of ethanol
† Coordinate "y, mm" should be increased by 0.5 mm for data marked with dagger.
