Recent supercomputer advances enable 3-D Direct Numerical Simulation (DNS) of turbulent combustion to be performed. In oral presentations, computer-graphic animations of such results extensively demonstrate the 3-D movement of the flame front and its interaction with turbulent eddies. Only a limited amount of experimental data are available, however, that can be compared with the 3-D DNS results because of great experimental difficulties in measuring 3-D flame-front movements and configurations. It is therefore desirable to establish a definitive technique to measure the 3-D movement and configuration of a flame front in premixed turbulent flames. In the present study an attempt is made to establish such an experimental technique, by use of a four-element electrostatic probe.
