Following, you would utilize this boundary ailment and solve for Fourier's 2nd Law to obtain the internal temperature distribution. Assuming no internal warmth era, the solution is ρ C p ( ∂ T ∂ t + v → ▽ T ) = k ▽ T displaystyle rho C_ p ( partial T more than partial t + overrightarrow v bigtriangledown T)=kbigtriangledown T MIG/MAG
