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 oil-film interferometry skin-friction technique is described and applied to flows in some of
the NASA Ames large wind tunnel facilities. Various schemes for applying the technique are …

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 …

The principles of a luminescent oil-lm skin-friction meter are described. Unlike the
interferometric oil-lm methods, this technique measures skin friction by detecting …

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 …

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 …

The application of photogrammetry to the measurement of skin friction using oil-film
interferometry is discussed. Oil-film interferometry and photogrammetry are first described to …

The benefits of analyzing multiple interferogram images obtained using oil-film
interferometry in order to determine wall shear stress are assessed. Both dual-and multi …
