Gas - gas and gas - solid laminar flat plate diffusion flame in microgravity: Structure and stability
- 92 Downloads
The structure and the stability of a laminar diffusion flame established over a flat plate was studied in micro-gravity and for low Reynolds number. A two stages program was developed and tested during parabolic flights, drop tower and finally aboard a sounding rocket. Three different regimes were established either for gas-gas or gas-solid systems: two stable regimes for blue and yellow flames, a transition regime between the two and the extinction or non-propagating zone.
