The aim of this work is to carry out experiments and numerical simulations to study the turbulence-combustion interaction in a nonpremixed hydrogen-air ame stabilized in a bluff body wake. For this purpose, are used a PIV technique for the determination of two velocity components and a PLIF technique to determine the uorescence intensity of the chemical species OH, which is a good indicator of the flame front location. PIV post-processing methods are evaluated in order to maximize the spatial resolution of the technique and to remove spurious instantaneous velocity vectors. In addition, the burner is modeled in ANSYS / FLUENT and the simulation results are validated by comparisons with the experimental results. Models based in the Reynolds avareges are used to characterize the turbulence and a flamelet model is adopted to describe combustion. The experimental results indicates that, for the ow rates of air and hydrogen adopted, combustion occurs in the flamelet regime, where the flame front is wrinkled, but without discontinuities. The reactive cases simulations did not agree with the experimental results, indicating that the computational mesh needs to be improved.
