Measurements of Turbulent Flame Speed and Integral Length Scales in a Lean Stationary Premixed Flame

Klingmann, Jens LU and Johansson, Bengt LU (1998) In SAE Technical Paper Series 107(SAE Technical Paper 981050).
Abstract
Turbulent premixed natural gas - air flame velocities have

been measured in a stationary axi-symmetric burner using LDA. The flame was stabilized by letting the flow retard toward a stagnation plate downstream of the burner exit. Turbulence was generated by letting the flow pass through a plate with drilled holes. Three different hole diameters were used, 3, 6 and 10 mm, in order to achieve different turbulent length scales. Turbulent integral length scales were measured using two-point LDA and the stretching in terms of the Karlovitz number could be estimated from these measurements. The results support previous studies indicating that stretching reduces the flame speed.
