Time to Ignition (Thermally Thick Solids)

introduction_to_fire_dynamics_chapter_6_equation_6_32

Calculates the time to ignition for thermally thick solids using Drysdale's equation 6.32.

Equations

t_{ig} = \dfrac{\pi}{4} \cdot k \cdot \rho \cdot c \cdot \left( T_{ig} - T_o \right)^{2} \cdot \dfrac{1}{\dot{Q}''_{R} ^{2}}
