Abstract

Direct Numerical Simulation (DNS) of transport of multiple passive scalarswith varying molecular diffusivity in a spatially evolving low-swirl axisymmetric swirling jet isperformed at a Reynolds number of 1500. The swirling jets discussed are limited to non-vortexbreakdown fl ow. Multiple passive scalars with differing molecular diffusivity are introduced intothe jet and allowed to evolve with the fl ow fi eld. The DNS result reveals that the scalar decay varieswith the jet swirl number as well as the Schmidt number corresponding to the scalar. Furthermore,the scalar decay exhibits non-linearity.
