Surface Flame Spread - The Thermally Thin Case

2 Surface Flame Spread - The Thermally Thin Case 

We will develop an analytical formulation of the statement in Equation (8.2). This will be done for surface flame spread on solids, but it can be used more generally [1], As with the ignition of solids, it will be useful to consider the limiting cases of thermally thin and thermally thick solids. In practice, these solutions will be adequate for first-order approximations. However, the model will not consider any effects due to 

We apply Equation (3.45) for the CV fixed to x = xp. The solid with density p and specific heat cp appears to enter and leave the CV with velocity vp, the flame speed. Thus, 

FIRE SPREAD ON SURFACES AND THROUGH SOLID MEDIA 

This can be put into a different form to reveal the relationship of flame spread to ignition
