This paper reviews three relatively modern categories of skin-friction measurement
techniques that are broadly classified as microelectromechanical systems (MEMS)-based …

SKIN friction, along with surface pressure and temperature, is one of the most important
surface quantities in aerodynamics and fluid mechanics. It is also the most difficult surface …

The feasibility of skin-friction field measurements using the global luminescent oil-film skin-
friction field estimation method was evaluated for a challenging case of a supercritical airfoil …

Extraction of high-resolution skin-friction fields from surface flow visualization images as an
inverse problem is discussed from a unified perspective. The surface flow visualizations …

A data analysis method based on the linear least-squares (LLS) method was developed for
the extraction of high-resolution skin friction fields from global luminescent oil film (GLOF) …

The experimental conditions required for a turbulent channel flow to be considered fully
developed and nominally two dimensional remain a challenging objective. In this study, we …

Wall shear stress and wall streamline direction measurements were conducted on a generic
delta wing model to demonstrate the potential of the white-light oil-film interferometry in three …

An experimental characterization of transonic, turbulent, separated flow generated by an
axisymmetric model is presented, with intent for use as a computational validation case. The …

The luminescent oil film flow tagging skin friction meter is presented and used to collect time-
averaged spatially distributed skin friction data on the surface of NASA's FAITH model. The …

Results from a skin-friction-field measurement method using global luminescent oil-film
images, in which the oil film covers a large portion of the surface, were examined by …
