Abstract

Experimental data for a series of spray flames is utilized to perform analysis of validation studies conducted by multiple contributors. In this multiphase context, various choices for boundary conditions as well as modeling frameworks and formulations are evaluated. Both large eddy simulation (LES) and Reynolds-averaged Navier-Stokes (RANS) approaches showed the ability to capture droplet evolution with regards to mean and fluctuating velocities. This accuracy is contingent on the proper specification of both droplet and gas phase velocities at the jet exit. The combined effect of combustion and evaporation model choices impacts the downstream volume flux of droplets and resulting gas phase temperature. Further investigation is required to isolate individual model effects for high-temperature spray-laden environments. Proposed solutions involve the simulation of a wider array of flow conditions or lowerlevel experiments to remove the effects of model coupling.
