In this paper, a numerical parametric study has been conducted to examine the effects of varying both inlet turbulent intensity and angle of attack for a bluff body flame holder (V-gutter) in a channel. The geometry used was based on previous experiments. The inlet turbulent intensity was varied from 2% to 100% while the angle of attack of the V-gutter was varied from −20° to 20°. The turbulent flow was modeled with a RANS-based realizable k-ε turbulence model. The combustion setup used was premixed propane-air combustion with an equivalence ratio of 0.6. The combustion-turbulence interaction is simulated with an eddy-dissipation model. Calculations were carried out using a finite volume based solver, and all equations were solved using the second order upwind method. Results indicate that increasing the inlet turbulent intensity and V-gutter angle of attack will result in an increase not only in the size but also in magnitude of the downstream high turbulence areas with vortexes.
