The role of freestream turbulence scale in subsonic flow separation [PDF]

open access: yes
The ojective of this work is the clarification of the role of freestream turbulence scale in determining the location of boundary layer separation. An airfoil in subsonic wind tunnel flow is the specific case studied.

Hot-Wire Attenuation and Its Correction in Turbulence Measurements [PDF]

open access: yes, 2007
A scheme is proposed for correcting the hot-wire attenuation in turbulence measurements in both frequency and time domains. The scheme is tested for simulated hot-wire signals under velocity impulse and sinusoidal perturbations of various frequencies. It

Development of subminiature multi-sensor hot-wire probes [PDF]

open access: yes, 1988
Limitations on the spatial resolution of multisensor hot wire probes have precluded accurate measurements of Reynolds stresses very near solid surfaces in wind tunnels and in many practical aerodynamic flows.

Optimizing the Parameters of Hot-wire CNC Machine to Enhance the Cutting of Plastic Foam

open access: yesAl-Khawarizmi Engineering Journal, 2019
Hot-wire cutting is one of the important, non-traditional thermomechanical way to cut polymer, usually expanded foam and extruded foam, in low volume manufacturing.

Shearing-Stress Measurements by use of a Heated Element [PDF]

open access: yes, 1954
The rate of local heat transfer from a solid surface to a moving fluid is related to the local skin frinction. Measurements of the heat transmission from small elements embedded in the surface of a solid can thus be used to botain local skin-friction ...
