Development of a direct-force-reading, thin-film shear stress gage
A thin-film gage was designed, constructed, and tested for the measurement of skin friction in steady and non-steady flows. This direct-force-reading gage is designed to have a high frequency response (> 1 kHz), high temperature capability (800 K), and full directional sensitivity in both subsonic …

Time-resolved heat transfer measurements and analysis in the wake region of a cylinder in crossflow
A thin-film gage was used to measure the fluctuating component of heat transfer from a cylinder placed in a steady crossflow at Reynolds numbers, based on cylinder diameter, of approximately 19,000 and 30,000. Further, a one-dimensional flow pulsation at 13 Hz was added to the mean flow at a …

Design and calibration of a rapid-response thin-film heat flux gage
… boundary conditions. The measuring element is a thin-film heat flux gage made by sputter-coating gold on a substrate. A constant-temperature anemometer is used to maintain the thin-film gage at a specified temperature under fluctuating conditions. A separate temperature control system maintains …

Turbine Blade Heat Transfer Measurements in a Transonic Flow Using Thin Film Gages
… wind tunnel with the data collected using thin film gages. All of the necessary development to use the thin film gages has been completed, including construction of electronics and analysis tools to reduce the data. Gage installation and calibration techniques have been successfully …

Effects of Tip Clearance Gap and Exit Mach Number on Turbine Blade Tip and Near-Tip Heat Transfer
… infrared thermography technique. In addition, thin film gages were used to study similar effects on the near-tip regions at 94% based on engine blade span of the pressure and suction sides. The experiments were conducted at the Virginia Tech transonic blow-down wind tunnel facility with a …
