Flame-standoff ratio

To write simple formulas it is useful to define v = (vp Wp/vg Wo)io, oo > the product of the stoichiometric mass ratio of fuel to oxidizer with the oxidizer mass fraction at infinity. Then equation (62) for the flame-standoff ratio becomes... 

Subsequently the droplet surface area regression rate the flame-front standoff ratio y, and the flame temperature Tt are all constants of the... 

Fig. 5 Non-dimensional flame standoff distance and Peclet number based on flame standoff distance (ratio of bulk-to-diffusion velocity) for benchmark case (Table 1). Note that in dimensional terms xg for small Eg is actually greater than that for large Eg for comparable...

Figure 5 also shows the Peclet number based on the flame standoff distance, Pe = Xgfh, which can be interpreted as the ratio of the bulk convective velocity to diffusion velocity Pe = ul DIXg) = ul ag IXg)). In the intermediate pressure...
