This work presents Large Eddy Simulation (LES) of a laboratory scale RQL combustion chamber. Simulations were carried out using an in-house LES-code for reactive, two-phase, adiabatic flow implemented in OpenFOAM. The twophase turbulent reactive flow is modeled following a coupled Euler-Lagrange approach in combination with a presumed Joint Probability Density Function (JPDF) combustion model and tabulated chemistry. The reaction
progress of laminar premixed flames is tabulated using a kerosene-surrogate chemical reaction mechanism. Calculated and measured velocity fields of the gaseous and liquid phase are compared to each other for reacting and non-reacting conditions. The results show excellent agreement between the two-dimensional flow fields derived from PIV and LES for the non-reactive case. The results of the reactive case show very good agreement for the velocity field.
