How is furnace thermal analysis different from typical electronics cooling?
Industrial furnaces operate at 600-1400 C where radiation dominates — scaling as T^4 versus T for convection. Participating media (combustion gases) emit and absorb radiation, requiring radiative transfer equation solvers. The goal is process uniformity across a large batch, not cooling a single component.
What causes distortion during quenching and how is it simulated?
Quenching creates temperature gradients — the surface cools first and wants to contract while the hot core resists, creating thermal stresses. When the surface reaches martensite start temperature, transformation-induced volume expansion adds to thermal stresses. Accurate simulation requires three-way coupling of heat transfer, phase transformation kinetics, and mechanical analysis.
