“…In their paper on the mixing in a self-preserving axisymmetric turbulent jet, Fukushima et al 13 compared their results obtained from PIV and PLIF techniques with not only the results from DNS, but also with point velocity measurements and combined PIV, particle-tracking velocimetry (PTV), or laser Doppler velocimetry (LDV) with laser-induced fluorescence (LIF) measurements, and found satisfactory agreement between the DNS simulations and the data collected using each technique. Meyer et al 14 also measured the velocity field and concentration field using PIV and PLIF. They considered the mixing of a jet in a crossflow in a square duct and compared their results with measurements in the same setup by the use of pointwise LIF and laser Doppler anemometry (LDA).…”

Experiments are carried out for passive mixing in order to obtain local mean and turbulent velocities and concentrations. The mixing takes place in a square channel with two inlets separated by a block. A combined PIV/PLIF technique is used to obtain instantaneous velocity and concentration fields. Three different flow cases are studied. The 2D numerical predictions of the mixing channel show that none of the k -turbulence models tested is suitable for the flow cases studied here. The turbulent Schmidt number is reduced to obtain a better agreement between the measured and predicted mean and fluctuating concentrations. The multi-peak presumed PDF mixing model is tested and comparisons with experiments are encouraging.KEYWORDS: mixing, PIV, PLIF, CFD, mass transfer, probability density function * The following foundations are acknowledged for their financial support to the laser laboratory at Aalborg University Esbjerg: Lida og Oscar Nielsens fond, Fabrikant Mads Clausens fond, Esbjerg seminarie fond, Direktør Ib Henriksens fond, Fabrikant P.A.

Turbulent mixing in a confined wake flow was studied by using the combined PIV/PLIF technique to measure instantaneous concentration and velocity fields. Measurements were performed at two slightly overlapping areas in the initial mixing zone and at an area at the end of the channel. The measurements revealed that there is a recirculation zone right behind the block that gives an increased mixing effect in this area. The measurement at the end of the channel shows that the concentration distribution is quite uniform, but the two streams are not completely mixed.
