Experimental and numerical study of turbulent flame structures of a spray jet flame

The flame structure of a laboratory scale n-heptane spray flame is investigated experimentally and numerically. The experimental burner is an open chamber with an ambient temperature co-flow surrounding a hollow cone simplex atomiser. OH-PLIF measurements are performed to study the interaction between turbulence, droplets, and chemistry. The simulation is performed using a Large Eddy Simulation with combustion modelling included by means of the solution of the transport of the joint-sgs probability density function using the stochastic fields method with promising results.
