Cylindrical heat transfer

WebThe heat flow, transfered through a solid cylindrical wall, separating two fluids with different temperatures, is calculated by the following formula in the simplest case: q = K × (Tf1 - Tf2); K - heat transfer coefficient; Tf1 , Tf2 - are the temperatures of fluids between which the heat exchange takes place. 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.
