چکیده
Flow-induced vibration is an enthralling phenomenon in the field of engineering. Numerous studies have been conducted on converting flow kinetic energy to electrical using fundamental. Wake-induced one configurations used optimise generation electricity. The results study effect gap between multiple bluff bodies will provide insight into optimising harvesting process. This focuses fluid behaviour and response behind two circular cylinders arranged tandem when interacting with a at low Reynolds numbers ranging from 200 1000. has done several lengths cylinders, 2D 5D. was carried out numerically by OpenFOAM. At Re = 1000, it found that length 2.5D optimal terms producing highest lift force coefficient downstream cylinder.

Turbulence Modelling of Deep Dynamic Stall at Low Reynolds Number
The unsteady separated turbulent flow around an oscillating airfoil pitching in a sinusoidal pattern in the regime of low Reynolds number is investigated numerically employing the URANS approach with two advanced turbulence models, namely the RNG kmode and Transition SST model, and the DES approach based on the SST kmodel. A comparison with experimental data shows that the SST kbased D...
متن کاملLow-Reynolds-number swimming at pycnoclines.
Microorganisms play pivotal functions in the trophic dynamics and biogeochemistry of aquatic ecosystems. Their concentrations and activities often peak at localized hotspots, an important example of which are pycnoclines, where water density increases sharply with depth due to gradients in temperature or salinity. At pycnoclines organisms are exposed to different environmental conditions compar...
متن کاملQuiet swimming at low Reynolds number.
The stresslet provides a simple model of the flow created by a small, freely swimming and neutrally buoyant aquatic organism and shows that the far field fluid disturbance created by such an organism in general decays as one over distance squared. Here we discuss a quieter swimming mode that eliminates the stresslet component of the flow and leads to a faster spatial decay of the fluid disturba...
متن کاملCompensatory escape mechanism at low Reynolds number.
Despite high predation pressure, planktonic copepods remain one of the most abundant groups on the planet. Their escape response provides one of most effective mechanisms to maximize evolutionary fitness. Owing to their small size (100 µm) compared with their predators (>1 mm), increasing viscosity is believed to have detrimental effects on copepods' fitness at lower temperature. Using high-spe...
متن کاملA circle swimmer at low Reynolds number.
Swimming in circles occurs in a variety of situations at low Reynolds number. Here we propose a simple model for a swimmer that undergoes circular motion, generalising the model of a linear swimmer proposed by Najafi and Golestanian (Phys. Rev. E 69, 062901 (2004)). Our model consists of three solid spheres arranged in a triangular configuration, joined by two links of time-dependent length. Fo...
