Abstract : A summary of the research performed under this grant is provided. It consists of work that bears on reacting flow research as well as basic turbulence studies. In the former category, the research involves differential diffusion, photobleaching, conditional scalar dissipation, helium jets, and the thickness-distribution of OH regions in diffusion flames. In the former category, the summary is limited to Kolmogorov's refined hypothesis, self-affine traces of turbulent signals, synthetic turbulence, wavelet decomposition of turbulence and the intermittency exponent in the turbulence dissipation. Only briefly mentioned are other aspects such as the scaling of structure functions, the scaling of circulation and the effect of filtering on Kolmogorov's 4/5 relation.
