Heat Flux Based Upon Measured Temperatures

[mullins]

I have a combustion chamber where 26 thermocouples have been attached to measure the temperature of the inside wall of the chamber. I know the material properties and I was wondering if there was a way to determine the heat flux through the combustion chamber wall as a function of time since the actual combustion activities were controlled. At least is it possible to determine the heat flux at a given point knowing the internal wall temperature and position?
