WebApr 8, 2024 · The heat transfer strength may increase due to the intense turbulence caused by the introduction of the impingement. Compared with the cylindrical hole, the laid-back hole has a spanwise expansion feature, which makes the shape of the high heat transfer region wider in the spanwise direction and increases the heat transfer level. WebMay 22, 2024 · The cylindrical coordinates don't make any difference. The physical boundary condition is that the radial heat flux on each side of the boundary is the same. That means k 1 d T d r 1 = k 2 d T d r 2 where k 1 and k 2 are the thermal conductivities of the materials on each side of the boundary.
