Effect Of Air Velocity On The Length Of Flame In Turbulent Non-Premixed Flames

Abstract
In this study, the turbulent non-promixed methane-air flame is simulated to determine the effect of air velocity on the length of flame. The computational fluid dynamics (CFD) technique is used to perform this simulation. To solve the turbulence flow, k-ε model is used. In this study, contrary of some of the past works, the material properties are considered variable in each of the simulations and obtained results are compared with them. Finally, it is achieved that at a certain flow rate of fuel, increasing the air velocity, as expected, like when the properties were considered constant, causes an increase on the flame temperature, leads to a thinner flame.
