Processes during droplet combustion

(Figure 30.1)
 

Factors affecting the shape of the flame front:

Condition under which combustion takes place!

Zero gravity
: Spherical flame front (No buoyancy)
Normal gravity
: Elongated (Due to natural convection)
Forced convection condition
: Fame aligned with flow

Energy required to vaporize the liquid fuel:
