Design and calibration of a rapid-response thin-film heat flux gage
A local heat-flux measurement system was built, calibrated and tested for use in unsteady flows. The system was designed to maintain constant wall temperature boundary conditions. The measuring element is a thin-film heat flux gage made by sputter-coating gold on a substrate. A constant-temperature …

The simultaneous measurement of time-resolved surface heat flux and freestream turbulence at a stagnation point
Two rapid-response thin-film heat flux gage systems have been used to measure time-resolved unsteady heat transfer signals. The Heat Flux Microsensor is a passive gage which measures the temperature difference across a thin thermal resistance. The second sensor, an actively powered gage operated by …

Development of a Direct-Measurement Thin-Film Heat Flux Array
A new thin film heat flux array (HFA) was designed and constructed using a series of nickel/copper thermocouples deposited onto a thin Kapton® polyimide film. The HFA is capable of withstanding temperatures up to 300 °C and produces signals of 42 μV/(W/cm²). As a result of its thin film …

Development of a Novel, Manufacturing Method of Producing Cost-Effective Thin-Film Heat Flux Sensors
A new method of manufacturing heat flux sensors was developed using a combination of copper etching and stencil printing nickel/silver conductive ink thermocouple materials onto a thin-film polyimide Kapton® substrate. The semi-automated production capabilities of this manufacturing process …
