Abstract

A method is presented to calculate the critical flow velocity in heat exchangers. The method combines the fluid dynamic force caused by cross flow and the vibration characteristics of the complicated tube array to obtain its response. Not only is the vibration mode of tube array and nonuniformity of velocity and density distribution of cross flow taken into account, but also the effect of antivibration devices, such as spacer, connecting band, and so on, is estimated. Numerical examples of constrained single-tube array, multi-tube array in reversed flow, and a group of panels with spacers are described.
