Implementation of large scale PIV measurements for wall bounded turbulence at high Reynolds numbers
Here we describe the application of a multiple camera planar particle image velocimetry (PIV) measurement to achieve a large field of view (FOV) in a high Reynolds number turbulent boundary layer. Measurements are performed over a FOV of 0.8m × 0.5m (2.25δ × 1.4δ, where δ denotes the boundary layer thickness) in the streamwise and wall-normal directions respectively in a turbulent boundary laye...
متن کاملNested multi-resolution PIV measurements of wall bounded turbulence at high Reynolds numbers
Here we describe the use of a nested high magnification camera configuration within a large field of view (FOV) PIV experiment. The objective of these measurements is to obtain instantaneous velocity flow fields to resolve the wide range of scales present in turbulent boundary layers at high Reynolds numbers of up to Reτ ≈ 20000. Flow statistics are compared against previous measurements made u...
متن کاملNear Field Measurements of an Axisymmetric Turbulent Jet at Low Reynolds Numbers: A PIV and CTA Comparison
This paper presents a comparison between two commonly used velocity measurement techniques applied in experimental fluid dynamics: Constant Temperature Anemometry (CTA) and Particle Image Velocimetry (PIV). Previous studies have applied these techniques to the self-similar region of an axisymmetric jet which resides in the far-field. However, there is a lack of CTA to PIV comparison data in the...

متن کاملOn the suitability of steady RANS CFD for forced mixing ventilation at transitional slot Reynolds numbers.
UNLABELLED Accurate prediction of ventilation flow is of primary importance for designing a healthy, comfortable, and energy-efficient indoor environment. Since the 1970s, the use of computational fluid dynamics (CFD) has increased tremendously, and nowadays, it is one of the primary methods to assess ventilation flow in buildings. The most commonly used numerical approach consists of solving t...
