Ignition in Thermally Thin Solids

Note that if this net flux is for a heat flux meter cooled at 7 ,XJ, the ambient temperature, the gage directly measures the external incident radiative and flame heat fluxes. 

Let us return to our discussion of the prediction of ignition time by thermal conduction models. The problem reduces to the prediction of a heat conduction problem for which many have been analytically solved (e.g. see Reference [13]). Therefore, we will not dwell on these multitudinous solutions, especially since more can be generated by finite difference analysis using digital computers and available software. Instead, we will illustrate the basic theory to relatively simple problems to show the exact nature of their solution and its applicability to data.
