RISNear-Wake Characteristics and Acoustic Resonance Excitation of Crimped Spirally Finned Cylinders in Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of the near-wake flow characteristics for isolated crimped spirally finned cylinders in cross-flow and its influence on the generated sound pressure during flow-excited ...
Applicability of the Equivalent Diameter Approach to Estimate Vortex Shedding Frequency and Acoustic Resonance Excitation From Different Finned Cylinders in Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article explores the applicability of utilizing different equivalent diameter (Deq) equations to estimate the vortex shedding frequency and onset of self-excited acoustic resonance for various types of finned cylinders. ...
Vorticity Shedding and Acoustic Resonance Excitation of Two Tandem Spirally Finned Cylinders in Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aeroacoustic response of two tandem spirally finned cylinders is experimentally investigated. Three different pairs of finned cylinders are studied with fin pitch-to-root diameter ratios (p/Dr) ranging between ...
Applicability of Nonuniformly Varying the Fin Density of Tandem Finned Cylinders as a Viable Vortex and Noise Suppression Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the use of nonuniform finned tubes in tandem arrangements with different spacing-to-average equivalent diameter ratios (L/Deq(avg)) to suppress flow-induced acoustic resonance. Particle image ...
