This is the second volume of a two-volume guide to designing, conducting and interpreting
laboratory and field experiments in a broad range of topics associated with hydraulic …

An accurate and straightforward skin-friction measurement procedure over a three-
dimensional (3D) bump geometry is proposed. The procedure employs oil-film …

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 application of oil film interferometry (OFI) for the measurement of global skin friction on
the surface beneath a complex three-dimensional supersonic flow is explored in this study …

An experimental characterization of the flow environment for the Sandia Axisymmetric
Transonic Hump is presented. This is an axisymmetric model with a circular hump tested at a …

In this study, we developed a novel optical-flow algorithm for determining the wall shear-
stress on the surface of objects. The algorithm solves the thin-oil-film equation using a …

As the overall pressure ratio (OPR) and turbine inlet temperature (TIT) of modern gas
turbines are constantly being increased in the pursuit of increasing efficiency and specific …

Despite being one of the most relevant quantities to characterize the flow close to a solid
boundary, direct and accurate measurements of wall-shear stress have not been available …

Flow shear stress measurement plays an important role in the characterization of macro and
microfluidic systems. Many currently used wall shear sensors quantify local shear stress with …
