要約

Experimental results are reported which have been found out at five several tube banks in the Reynolds number range 2×l03 ≤ Re ≤10 5. The yaw angle was varied between 15°≤ φ ≤ 90° (cross flow). The tests have shown that the principle of independence can be applied to predict the heat transfer coefficient of yawed tube banks. However, it is not suitable to describe the hydraulic resistance. Generally the hydraulic resistance coefficient increases with smaller yaw angle in the subcritical Reynolds number range. Besides, the dependence on the Reynolds number varies with the yaw angle.
