VORTEX-INDUCED VIBRATION CHARACTERISTICS AND HEAT TRANSFER MECHANISM OF AN OSCILLATING PLATE ATTACHED TO A CYLINDER IN A CONSTANT-TEMPERATURE CHANNEL
RESUMO
In the present study, a passive technique for heat transfer enhancement was used to affect the turbulence and eddies via an oscillating plate in a flow. The movement of the plate in the fluid domain was solved by a two-way fluid-solid interaction analysis. The increase in heat transfer by this method caused an increase in the friction coefficient, and paying attention to the heat transfer and pressure loss simultaneously is important. The role of the cylinder shape, cylinder location, and the length of the flexible plate in the heat transfer and pressure loss were investigated. It can be concluded that a bluff body before the oscillating plate can improve the performance evaluation criterion (PEC) by 13.75%. In addition, reducing the length of the plate by half can reduce the PEC number by 8%. The shape of the cylinder also has a significant effect on the heat transfer ratio and pressure loss. The best case was one with a circular cylinder behind the oscillating plate with a larger length with a PEC of 0.8.
