Abstract

This research investigates heat transfer phenomena on a plate used with impinging electric field flames; i.e., flames burning in the presence of an electric field. Electric field effects on flames have been investigated in different applications but not when the flames are impinging on nearby surfaces. Challenges to measurement methods when an electric field is applied in the system have limited the understanding of changes to the temperature distributions and species concentrations caused by the field. This study uses an infrared forward looking infrared (FLIR) camera with Schlieren visualization to examine the heat flux from flames over an impinging plate with different electric fields applied. In particular, we study the electric field effects on flames when those flames transfer heat to a nearby plate, and then how that transfer can be controlled using the electric field. The results show that electric fields affect substantially the heat flux distribution through the ion-driven wind, particularly when the plate location is just above the flame tip.
