    Experiment study of a scalar mixing layer using reactive and passive scalars

    The reactive scalar mixing layer in grid generated turbulence similar to that of Bilger et. al. (1991) has been repeated after a modification to the experiment set-up. The various statistics of the mixture fraction (a conserved scalar) deduced from reacting and nonreacting measurements of concentration are presented. The data do not show the uncharacteristic behaviour in the centre of the mixing layer any more and agree well with the data obtained from the thermal mixing layer of the other sources
