Show more >This paper mainly describes the laser based method we developed for quantitative measurements of soot volume fraction applied in two turbulent flames of diesel and E85 (gasoline/ethanol mixture) stabilized on a home-made jet burner working with liquid fuels. The two flames have been studied by keeping constant the lower heating value (LHV) at atmospheric pressure. The diesel flame was a normal sooting flame which generates soot particles from inception to mature stage. The second flame was an E85 flame producing very small amounts of soot particles that do not undergo or very limited surface growth along the height above the burner. We propose here a new auto-calibrated laser induced incandescence method for the detection system specifically develop to directly determine the soot volume fraction (fv) in sooting turbulent diffusion flame, relying on the LII spectrum measurement. The experiments were carried out by using a laser at 532 nm and required the temperature determination along the vertical center line of the flame necessary for the determination of the soot absorption function Em(λ). This parameter allows to decrease the uncertainty for the soot volume fraction (fv) value. The maximum soot volume fraction in the diesel flame around 951 ppb and 13 ppb in the flame E85 were determined this way, highlighting the very weak soot formation with the studied biofuel.Show less >
