We report the combined application of Ramanography and particle image velocimetry (PIV) for the investigation of gas mixing processes. A droplet seeded hydrogen flow was injected as a free jet into pressurized nitrogen at 0.95 MPa. Ramanography and PIV were used to quantitatively image the mixture composition and the flow field of the mixing process, respectively.
