Influence of freestream turbulence on the near-field growth of a turbulent cylinder wake: Turbulent entrainment and wake meandering
نویسندگان
چکیده
The influence of freestream turbulence (FT) on near-field development turbulent wakes is assessed with regards to both the entrainment rate background fluid into wake and extent meandering. It shown that FT increases near wake, thereby at which spreads. meandering more complex, but it integral length scale dominant property affecting In a novel control experiment, large-scale coherent motion in suppressed, far-wake results are recovered: is, reduced via suppression small-scale nibbling.

An experimental study of entrainment and transport in the turbulent near wake of a circular cylinder
This paper describes an experimental investigation of transport processes in the near wake of a circular cylinder a t a Reynolds number of 140000. The flow in the first eight diameters of the wake was measured using X-array hot-wire probes mounted on a pair of whirling arms. This flying-hot-wire technique increases the relative velocity component along the probe axis and thus decreases the rela...
متن کاملStatistical Description in the Turbulent Near Wake of a Rotating Circular Cylinder
Turbulence studies were made in the wake of a rotating circular cylinder in a uniform free stream. The interest was to examine the turbulence properties at the suppression of periodicity in vortex formation process. An experimental study of the turbulent near wake of a rotating circular cylinder was made at a Reynolds number of 9000 for velocity ratios, λ between 0 and 2.7. Hot-wire anemometry ...
متن کاملThe Turbulent Wake of a Monopile Foundation
An experimental programme is presented, examining the turbulent wake of a monopile foundation in a current. Velocity was recorded across an extensive domain downstream of a model monopile in a 0.5 m deep basin, using an acoustic Doppler velocimeter array. The distribution of turbulent kinetic energy (TKE) is examined across the entire domain. Tests were undertaken using several combinations of ...
متن کاملEffects of Freestream Turbulence in a Model Wind Turbine Wake
The flow structure in the wake of a model wind turbine is explored under negligible and high turbulence in the freestream region of a wind tunnel at Re ∼ 7× 104. Attention is placed on the evolution of the integral scale and the contribution of the large-scale motions from the background flow. Hotwire anemometry was used to obtain the streamwise velocity at various streamwise and spanwise locat...
