Experimental study of the characteristics of flame jet in crossflow

The characteristics of flame jet into crossflow were experimentally investigated. The influences of the parameters of jet and main flow on jet penetration depth and temperature characteristics were studied under atmospheric pressure and temperature. The temperature field of jet flame and an expression of jet penetration depth were attained. Results show that the temperature of the flame jet decreases and boundary of the jet is widened along the jet trajectory. The penetration depth of jet flame increases with increasing ratio of jet and main flow's momentum. And, the penetration depth of jet flame was larger than cool jet under the same ratio of momentum.
