My understanding is that most of the heat in a kiln is transmitted by radiation, not convection. This would suggest the use of a reflective wall for the kiln to contain the heat.
So, for example, imagine we line the kiln with polished silver. Will the silver reflect the heat away until it is absorbed by the bolus, or will the air in the kiln just get so hot that it will melt the silver?If the latter is true, could we contain the kiln in a thin wall of a refractory ceramic interposed between the reflective wall and the heating area, then evacuate the air between the two?
Will the silver absorb some portion of the infrared radiation rather than reflect it? How can I model how much energy will be absorbed versus reflected?
How can I model something like this to explore what happens in a simulation? I have Mathematica. Is it as simple as entering in a few equations, or will it be very complicated to model?
Ultimately, I imagine there are 4 main variables: the temperature of the bolus, of the air in the chamber, of the heating elements and of the wall of the kiln.
