Investigation of Flame Generated Turbulence in a Large-Scale and Low-Intensity Turbulent premixed Flame With a 3-Element Electrostatic Probe And a 2-D LDV

摘要

An attempt has been made to examine the flame-generated turbulence in a large-scale and low-inten- sity turbulent premixed flame by measuring change of the local gas-velocity vector across the flame font in relation with local movement of the flame front. In order to achieve this measurements, spe- cially arranged diagnostics, composed of an electrostatic probe with three identical sensors and a two-color four beam LDV (laser-doppler velocimeter) system, have been adopted.
