An understanding of flame propagation needs the knowledge of the flame location and of the velocity field near the front. Time resolved laser Tomography coupled with high resolution cross correlation PIV has been developed. The method is based on the use of a copper vapor laser and a high-speed camera. The seeding level used for tomography provides an excellent resolution of the flame location and of the velocity vectors in the fresh gases. Experiment is conducted in a simulated engine where turbulence is controlled by means of a perforated grid. Interest is shown for the determination of laminar burning velocity and for the study of interaction between the flame front and the turbulent structures. Perspectives of stereoscopic PIV are also started on. It is shown that the existence of a normal component to the sheet plane of the velocity can lead to an erroneous flame velocity determination. |
