Surface Temperature, Heat Feedback, and Flame Standoff Distance

Surface Temperature, Heat Feedback, and Flame Standoff Distance 

The non-dimensional surface temperature 7 and conductive heat feedback are shown in Fig. 4 for the benchmark case (Table 1) as a function of Dg exp Eg /fj- As pressure (Dg) increases, surface temperature increases from the minimum value at the blowoff limit, namely Tg+Q +qj.lm (= 0.25) to the 

Therefore as P decreases, D increases. However, Xg also varies approximately as 

1/P at intermediate pressures therefore, the diffusion velocity D/xg is nearly independent of P. Yet u = Pg varies as P and at intermediate pressures, n is of order one (slightly less than one for Eg 1) so Pe and u are relatively
