Abstract

Three-dimensional numerical simulation was made for the hydrogen flame injected into the wake of a bluff-body type flameholder placed in an air stream. This analysis of the flame structure was aimed at designing the optimum combustion system of high performance. The velocity and pressure field were numerically solved using the SIMPLER algorithm. Turbulence model was based on Myong-Kasagi's low Reynolds number type k-ε model. The turbulent combustion was simulated by using Magnussen's eddy dissipation model. The simulated results showed a reasonable agreement with the species concentration profile observed in the wake.
