Abstract [en]
In boilers and heat exchangers devices, tube banks are used to transfer heat. One of the commonly used arrangement in heat exchangers are staggered tube banks, which consists of tubes arranged in triangular array form. The tube banks are characterized by their longitudinal and transverse pitch ratios, which is the pitch-to- diameter ratio. Based on the pitch ratio the tube bank is considered either a compact or a widely spaced tube bank arrangement. The tube bank may cause acoustic instabilities in the system. In this study, an investigation was performed to analyse the aero-acoustic properties of tube bank samples. Experiments were conducted for three staggered tube bank samples with pitch ratio varying from 1.2 (compact arrangement) to 2 (widely spaced arrangement). Passive properties determine the sound propagation through the system, while the active acoustic properties describe the acoustic source in the system. The attention is in this paper on the passive acoustic properties of staggered tube banks. The experimental results consist of scattering coefficients for samples with different pitch ratios and power balance for all three samples which are compared to see the pitch ratio effect on the acoustic properties.
