✦ Synopsis

laser-doppler measurements and particle track photographs of V-shaped flame are presented. The flame is stabilized behind a splitter plal~ in a two-dimensional premixed gas flow. In order to stabilize the flame, the splitter plate must be heated, indicating the importance of the thermal interaction between the flame and the plate. Based on theoretical concepts of the viscous flow at the trailing edge of a plate, an order of magnitude of the thermal penetration length is performed. This is compared with the preheat zone thickness.

In this article the steady-state process leading to ignition of a combustible mixture of hydrogen, oxygen, and nitrogen by a hot flat plate in a boundary layer flow is studied, including the effect of thermal diffusion. For sufficiently large values of the plate temperature, the ignition event corre
