Acoustic Instabilities on Swirling Flames

The POD makes possible to reduce the complete highdimensional acoustic field to a low-dimensional subspace where different modes are identified and let reconstruct in a simple way a high percentage of the variance of the field. Rotating modes are instabilities which are commonly observed in swirling flows. Such modes can appear under both cold and reacting conditions but that they have differen...

Direct numerical simulation of three-dimensional swirling n-heptane spray flames

Spray combustion is encountered in many engineering applications, such as internal combustion engines and gas-turbine aircraft engines. In these systems, the concurrent processes of liquid atomization, droplet evaporation, turbulent dispersion, and combustion interact and strongly affect each other, which makes experimental measurement and high-fidelity simulation challenging. To understand the...

Modeling of Moderately Swirling Turbulent Non-premixed Flames

Even if the goal of reducing NOx emissions pushes towards the use of premixed combustion, moderately swirling turbulent non-premixed flames are still widely employed in both industrial furnaces and gas turbines, because of their stable and safe behaviour in a wide range of fuels and operating conditions. Computational Fluid Dynamics (CFD) has become in recent years a key tool for the design of ...

A Numerical Study of Diffusive Effects in Turbulent Lean Premixed Hydrogen Flames

Three-dimensional direct numerical simulation of lean premixed hydrogen flames is used to explore the influence of species and thermal diffusion and viscosity on the flame structure and turbulent flame response. The leadingorder flame response is shown to be due to the global Lewis number with little influence from the other species. The previously-reported observation of decorrelation of fuel ...

Numerical modelling of double-diffusive natural convection within an arc shaped enclosure filled with a porous medium

Numerical study of double-diffusive natural convective heat transfer in a curved cavity filledwith a porous medium has been carried out in the current study. Polar system has beenselected as coordinate system. As a result, all equations have been discredited in r and θdirections. Brinkmann extended Darcy model has been utilized to express fluid flow inporous matrix in the enclosure. Smaller and...
