ABSTRACT
The main control equations include heat conduction, fluid flow, stress equivalent equations and the constitutive relations.
Heat conduction is governed by Fourier’s law is q T∇λ (1)
From Fourier’s law, we have the heat conduction equation
∂ ∂
= ∇T t
Tη 2
(2)
where η is thermal diffusivity, and
η λ ρ/c (3)
where λ ρ are thermal conductivity, specific heat and density of media respectively.
