| مستخلص: | The heat transfer of heat exchanger tubes is often enhanced by rolling external fins on to the tubes. These fins contribute to both the mass and the stiffness of the tubes. Calculations of the bending natural frequencies of finned tubes with only the mass contribution considered lead to values which are up to 10% lower than experimental values. A simple correction is derived to account also for the stiffening effect of the fins. With this correction good agreement with experiments is obtained. |
