TLDR
The results of an experimental investigation of a turbulent boundary layer with zero-pressure gradient directed toward extending the data base at low Reynolds numbers are presented in this article, where the data obtained are concerned primarily with mean velocity distributions, skin-friction coefficients, and distributions of intensity of the longitudinal component of the turbulent velocity fluctuations for Reynolds numbers based on momentum thickness as low as 465.
Abstract
The results of an experimental investigation of a turbulent boundary layer with zero‐pressure gradient directed toward extending the data base at low Reynolds numbers are presented. The data obtained are concerned primarily with mean‐velocity distributions, skin‐friction coefficients, and distributions of intensity of the longitudinal‐component of the turbulent‐velocity fluctuations for Reynolds numbers based on momentum thickness as low as 465. The validity, at low Reynolds numbers, of the semi‐empirical laws characterizing the inner and outer regions of the boundary layer is examined.

An original Pitot-static probe design for subsonic boundary layer investigation

TL;DR: In this paper, a Pitot-static probe is designed and developed to help in some boundary layer (BL) measurements, as for instance when average velocity profiles are required around models already available for wind tunnel tests but not provided with static pressure taps.

A single formula for the law of the wall and its application to wall-modelled large-eddy simulation

TL;DR: In this article, the logarithmic-exponential (LOG-EXP) formula was proposed to predict the mean velocity profile in different regions near the wall, and then a feed-forward neural network (FNN) was trained for the wall-modelled large-eddy simulation (WMLES) of turbulent channel flows.

Preliminary visualization study on the flat-plate boundary layer with continuous freestream turbulence

TL;DR: In this article, a very large-scale direct numerical simulations (VLS DNS) with over one billion mesh points on a set of three zero pressure-gradient, smooth, incompressible, flat-plate boundary layers (ZPGFPBL) is presented.

Demonstration of a laser vorticity probe in turbulent boundary layers

TL;DR: A laser-based probe for the nonintrusive measurement of velocity gradient and vorticity was demonstrated in turbulent boundary layers, and measurements were compared to those inferred from LDV measurements in the same facility and to data available in the literature.
