Parametric investigation of flow-sound interaction mechanism of circular cylinders in cross-flow
(2016-12-01)
Flow-excited acoustic resonance in heat exchangers has been an ongoing issue for the past century. The main challenge in this issue, is in the actual prediction of the resonance occurrence. This is due to the complexity ...
Flow-sound interaction mechanism of a single spirally finned cylinder in cross-flow
(2017-01-01)
Over the years, some effort has been expended in the improvement of heat transfer performance in tubular heat exchangers. This can be achieved by adding different types of fins to the outer tube surface, effectively ...
Effect of self-excited acoustic perturbations on flow characteristics around rectangular cylinders with varied geometrical aspects
(2023-08-01)
This study explores the effects of aspect ratio, edge geometry and incidence angles on the dynamic lift force, wake behaviors, and the susceptibility of such geometrical aspects to self-excited acoustic resonance in ...
Effects of the geometric modifications on the shear layer excitation source in co-axial side branches
(2023-08-01)
This comprehensive study delves into the interaction between shear layer oscillations and the acoustic field within co-axial cavities, spotlighting the efficacy of the sound source model as a reliable semi-empirical modeling ...
The aeroacoustics response and shear layer dynamics of confined cavities subject to low Mach number turbulent flow
(2023-04-01)
Cavities exposed to low Mach number flow in various engineering applications are often liable for generating flow-excited acoustic oscillations, resulting in large acoustic amplitudes and vibrations. This compromises the ...
