1
Q
Formula for heat flux across a surface
A
q = -k(dT(0,t)/dx)
T = (x,t)
2
Q
General heat conduction formula
A
Pc/k * dT/dt = d^2T/dx^2 + d^2T/dy^2 + d^2T/dz^2 + egen
3
Q
Convection conduction heat transfer through a surface
A
h[tinfin - T(0,t)] = -kdT(0,T)/dx

7
Q
Stephen Boltzmann law
Radiation and heat condition through surface equn
A
€*sigma[Tsurr^4 - T(0,t)^4] = -kdT(0,t)/dx
8
Q
Two different material heat conduction
A
Two heat conduction equations same distance. Different k value, different T value.
