Direct numerical simulations of chemically reacting turbulent mixing layer have been conducted to investigate effects of heat release on turbulent structures and fractal characteristics of turbulent scalar mixing. Fine scale eddies in roller structure and braid region are suppressed by dilatation induced by heat release. As the turbulent transition occurs, the fractal dimension increases linearly and reaches around 2.4. The development of the fractal dimension delays as a result of slower development of chemically reacting turbulence with heat release.
