| description | Abstract The investigations of flow-induced vibration have been around for decades to solve many engineering problems related to structural element. In a hindsight of advancing technology of microelectronics devices, the implementation of flow-induced vibration for energy harvesting is intrigued. The influence of downstream flat plate to flow-induced vibration experienced by a square cylinder is discussed in this study to surpass the limitation of wind energy due to geographical constraints and climate change. The mechanism of flow-induced vibration experienced by a square cylinder with downstream flat plate is numerically simulated based on the unsteady Reynolds Navier–Stokes (URANS) flow field. The Reynolds number, Re assigned in this study is ranging between $$4.2 \times 10^3$$ 4.2 × 10 3 – $$10.7 \times 10^3$$ 10.7 × 10 3 and the mass damping ratio designated for the square cylinder is $$m^*\zeta$$ m ∗ ζ = 2.48. The influence of three different flat plate lengths $$w/D = 0.5$$ w / D = 0.5 , 1 and 3 is examined. Each case of different flat plate is explored for gap separation between the square cylinder and the plate in the range $$0.5 \leqslant G/D \leqslant 3$$ 0.5 ⩽ G / D ⩽ 3 . Based on the numerical findings, the configuration of cylinder-flat plate with length $$w/D = 1$$ w / D = 1 has shown the highest potential to harvest high energy at comparatively low reduced velocity. |
