A comparative study of the velocity and vorticity structure in pipes and boundary layers at friction Reynolds numbers up to 10^4
Zimmerman, Spencer; Philip, Jimmy; Monty, Jason P; Talamelli, A.; Marusic, Ivan; Ganapathisubramani, Bharathram; Hearst, R. Jason; Bellani, Gabriele; Baidya, Rio; Samie, Milad; Zheng, X; Dogan, Eda; Mascotelli, Lucia; Klewicki, Joe (Journal article; Peer reviewed, 2019)This study presents findings from a first-of-its-kind measurement campaign that includes simultaneous measurements of the full velocity and vorticity vectors in both pipe and boundary layer flows under matched spatial ... -
Robust features of a turbulent boundary layer subjected to high-intensity free-stream turbulence
Hearst, R. Jason; Dogan, Eda; Ganapathisubramani, Bharathram (Journal article; Peer reviewed, 2018)The influence of the large scale organisation of free-stream turbulence on a turbulent boundary layer is investigated experimentally in a wind tunnel through hot-wire measurements. An active grid is used to generate ... -
Simultaneous skin friction and velocity measurements in high Reynolds number pipe and boundary layer flows
Baidya, Rio; Baars, W. J.; Zimmerman, Spencer; Samie, Milad; Hearst, R. Jason; Dogan, Eda; Mascotelli, Lucia; Zheng, X; Bellani, Gabriele; Talamelli, A.; Ganapathisubramani, Bharathram; Hutchins, Nicholas; Marusic, Ivan; Klewicki, Joe; Monty, Jason P (Book, 2019)Streamwise velocity and wall-shear stress are acquired simultaneously with a hot-wire and an array of azimuthal/spanwise-spaced skin friction sensors in large-scale pipe and boundary layer flow facilities at high Reynolds ... -
Spatial characteristics of a zero-pressure-gradient turbulent boundary layer in the presence of free-stream turbulence
Dogan, Eda; Hearst, R. Jason; Hanson, Ronald; Ganapathisubramani, Bharathram (Journal article; Peer reviewed, 2019)Particle image velocimetry (PIV) measurements are performed to examine the structural organization inside a turbulent boundary layer under the influence of free-stream turbulence (FST). In particular, streamwise-wall-normal ... -
Uniform-momentum zones in a turbulent boundary layer subjected to freestream turbulence
Hearst, Robert Jason; de Silva, Charitha; Dogan, Eda; Ganapathisubramani, Bharathram (Peer reviewed; Journal article, 2021)The instantaneous structure of a turbulent boundary layer that has developed beneath freestream turbulence (FST) was investigated with planar particle image velocimetry. Measurements were performed in the streamwise–wall-normal ...
