Journal ArticleDOI
Simultaneous measurements of scalar and velocity field evolution in turbulent crossflowing jets
Lester Su,M. G. Mungal +1 more
TL;DR: In this article, two flow configurations are studied, one in which the jet nozzle is flush with the tunnel wall and the other where the nozzle protrudes into the uniform region of the tunnel flow.
Journal ArticleDOI
The structure of fine-scale scalar mixing in gas-phase planar turbulent jets
Lester Su,Noel T. Clemens +1 more
TL;DR: In this article, fine-scale scalar mixing in gas-phase planar turbulent jets is studied using measurements of three-component scalar gradient and scalar energy dissipation rate fields.
Journal ArticleDOI
Experimental investigation of stabilization mechanisms in turbulent, lifted jet diffusion flames
Lester Su,O.S. Sun,M. G. Mungal +2 more
TL;DR: In this paper, a description of flame stabilization that depends on the large-scale organization of the mixing field is proposed, which is more consistent with theories based on partial fuel-air premixing than with those dependent on diffusion flame quenching.
Journal ArticleDOI
Quantitative planar imaging of turbulent buoyant jet mixing
TL;DR: In this paper, the authors used a planar Rayleigh scattering (RRS) image of axisymmetric turbulent helium jets issuing into air to obtain quantitative mixing measurements in a relatively near field, in which the jets are primarily momentum driven.
Proceedings ArticleDOI
Measurements of the three-dimensional scalar dissipation rate field in gas-phase planar turbulent jets
Lester Su,Noel T. Clemens +1 more
TL;DR: In this paper, a planar Rayleigh scattering and laser induced fluorescence is used to obtain 3D scalar and scalar dissipation rate field information in planar turbulent jets.
