Abstract

This paper presents an experimental investigation of the vorticity shedding and the susceptibility of acoustic resonance excitation for a square tube array with an intermediate tube spacing (i.e pitch-to-diameter ratio (P/D) of 1.73). The tube array could be rotated about an axis normal to the flow direction so that the effect of the flow approach angle could be investigated. Various Strouhal periodicities (St) were detected, and their strength, and value were dependant on the position measured within the tube bundle and the tube bundle's angular orientation. However, not all of the Strouhal periodicities measured caused self-excitation of acoustic resonance. This work illustrates the importance of considering the flow approach angle in the heat exchanger design phase to avoid the undesirable effects of acoustic resonance excitation during operation.

方管阵列的旋涡脱落和声共振激发:流动接近角的影响
本文对具有中间管间距(即节径比(P/D)为1.73)的方形管阵列的涡度脱落和声共振激发的易感性进行了实验研究。管阵列可以绕垂直于流动方向的轴旋转,从而可以研究流动接近角的影响。检测到了各种斯特劳哈尔周期性(St),其强度和值取决于在管束内测量的位置和管束的角取向。然而,并不是所有测量的斯特劳哈尔周期都引起了声共振的自激。这项工作说明了在热交换器设计阶段考虑流动接近角的重要性,以避免运行过程中声学共振激励的不良影响。

期刊介绍: The Journal of Pressure Vessel Technology is the premier publication for the highest-quality research and interpretive reports on the design, analysis, materials, fabrication, construction, inspection, operation, and failure prevention of pressure vessels, piping, pipelines, power and heating boilers, heat exchangers, reaction vessels, pumps, valves, and other pressure and temperature-bearing components, as well as the nondestructive evaluation of critical components in mechanical engineering applications. Not only does the Journal cover all topics dealing with the design and analysis of pressure vessels, piping, and components, but it also contains discussions of their related codes and standards. Applicable pressure technology areas of interest include: Dynamic and seismic analysis; Equipment qualification; Fabrication; Welding processes and integrity; Operation of vessels and piping; Fatigue and fracture prediction; Finite and boundary element methods; Fluid-structure interaction; High pressure engineering; Elevated temperature analysis and design; Inelastic analysis; Life extension; Lifeline earthquake engineering; PVP materials and their property databases; NDE; safety and reliability; Verification and qualification of software.
