There is good correlation between the Experimental Index, Nn, and the limiting velocity fraction V/Vc regardless of the gas composition of Nn. A line demarking the limiting Mach Number (V/Vc) is superimposed on the test data. Visually, this line segregates the dark flame-out data points from the light, stable flame data points. With graphical representation on log-log paper this line represents an equation of the form: For the tested 3 inch flare burner, the experimental factors \"a\" and \"s\" have been calculated: a = 0.0008 s = 4.0 -r^- = 0.0008 N4 vc The limiting exit velocity for stable burning for the experimental 3 inch flare burner can thus be estimated as a function of the Experimental Index to the fourth power. Application of this stability criteria to other burners is discussed in the following test observations. 5.2.19","restricted_i":0,"id":1883,"created_tdt":"2012-04-11T00:00:00Z","format_t":"application/pdf","parent_i":1892,"_version_":1642982780455354370}]},"highlighting":{"1883":{"ocr_t":[]}}}
