Based on recent laboratory experimental data by Feenstra et al. [1],[2] it has been determined that for larger test section widths, the maximum acoustic pressures generated during acoustic resonance were greater by more than a factor of four than those predicted by Blevins and Bressler [3]. We have evaluated a great number of resonant and non-resonant cases from inservice experience of full size steam generator and tubular heat exchanger tube banks in order to see the general vibratory behavior of the full size units. Fifteen vibrating and twenty-seven non-vibrating cases were evaluated and compared to the Feenstra et al. relationship. It is shown that on average the results from the full size units correlate well with the Feenstra et al. relationship. A gap exists between the vibratory and the non-vibratory cases. The non-vibratory cases produce acoustic pressures which are at or below the Blevins and Bressler relationship. From the results it can be concluded that the full size units, regardless of their size and also acoustic mode, produce high acoustic pressures at resonance, with the maximum acoustic pressure on average more than fifty to seventy five times higher than the input energy parameter defined by the product of Mach number and pressure drop through the tube bank. The results are tabulated and plotted for comparison.
