...N. J. Moore; S. D. Terry; K. M. Lyons Presented are the results of experiments designed to investigate flame lift-off behavior in the hysteresis regime for low Reynolds number turbulent flows. The hysteresis regime refers to the situation where the jet flame has dual positions favorable to flame...

.... An experimental campaign was carried out to identify the distribution of the pressure in the rotary ducts of the turbine. The results indicate the presence of a pressure gradient in the immediate vicinity of the inlet jet that is strongly attenuated when the ducts are not directly in contact with the...
