| description | In this work, the effect of acoustic waves on vortex shedding and convective heat transfer of two tandemly arranged cylinders is investigated using experiments and numerical simulations. This paper focuses on the average Reynolds number Re = 200, the sound pressure level ranges from 127dB to145dB, and the sound frequency ranges from 100Hz to 1000Hz. Different acoustic wave frequencies and particle vibration velocity amplitudes were set as the entrance conditions. The average heat transfer in the upstream and downstream cylinders was enhanced due to the increase in the particle velocity amplitude of the fluid around the cylinder by acoustic oscillations. Moreover, with the increase in the acoustic frequency, the flow mixing is enhanced and irregular vortices appeared in the cylindrical wake. With regards to the particle velocity amplitude, the values of the Nusselt number of the two cylinders increase with the increase in particle velocity amplitude. With the increase in the particle velocity amplitude, the forced mixing and heat transfer of the gap flow between the two cylinders are enhanced. The comparison between the experimental and numerical results shows that acoustic waves can enhance convective heat transfer of two tandemly arranged cylinders in the cross-flow. |
