Flow Field Considerations for Counter Flow Burners

Abstract

Many computational combustion tools (e.g. Sandia OPPDIF code) of opposed jet, counter flow diffusion flames apply a simplified potential flow model for the fluid flow portion of the problem. The resulting solution (for no flame) yields a stagnation region between the two burners and an axial velocity component that is independent of radius. S.C. Rolon recognized the need for experimental evidence to provide justification for a potential flow assumption. His results indicate that for a range of velocities and for two common burner designs (straight tubes with screens and dual converging nozzles) there are large discrepancies between the assumed flat radical profile and experimental measurements.
