Abstract
Turbulent jets and jet diffusion (non-premixed) flames are the basic flow configurations for many applications of reacting flows. In these flows, mixing of the reactants is important to achieve efficient combustion. A varying density can have large effects on the characteristic parameters in the flow, such as turbulence intensities, velocity and mixture fraction decay rates and spreading rates. This paper aims at characterising the variable density effects in axisymmetric jets and diffusion flames using a second order turbulence model, including buoyancy effects. Predictions are compared with experimental data from the literature, when available.
