Subsequent, you'll apply this boundary ailment and solve for Fourier's 2nd Legislation to get the internal temperature distribution. Assuming no inside heat era, the solution is ρ C p ( ∂ T ∂ t + v → ▽ T ) = k ▽ T displaystyle rho C_ p ( partial T about partial t + overrightarrow v bigtriangledown T)=kbigtriangledown T MIG/MAG is gre
