... working gas turbine, a simulation using a computational fluid dynamic (CFD) model calibrated with laboratory data would be an opted approach. To this end, the present study conducts a CFD model calibration against the database of two experimental cases including a slot impinging jet and three rows...

... coefficient. Experimental calibration systems were developed to simultaneously measure the heat flux gauge response relative to a secondary standard under the same flow and thermal conditions. The measured gauge sensitivities in the stagnation flow matched the model, and were used to estimate the value...

...Amanie N. Abdelmessih; Thomas J. Horn High heat fluxes are encountered in numerous applications, such as on the surfaces of hypersonic vehicles in flight, in fires, and within engines. The calibration of heat flux gauges may be performed in a dual cavity cylindrical blackbody. Insertion...

... as an efficient calibration tool for near-field thermal probes. Finally, an example of temperature measurements on a microhotplate has been presented, showing the potential of miniaturized wire thermocouples to perform thermal measurements on microscale object. We have calibrated a thermocouple cantilever...

... (a temperature outside the active range of the TLCs). The use of light transmission results in a larger range of temperature over which the TLCs can be calibrated and offers opportunities for more uniform lighting conditions, which may help overcome some of the problems associated with light reflection...

Phinney In this work, the use of Raman Stokes peak location and linewidth broadening methods were evaluated for thermometry applications of polysilicon microheaters subjected to evolving thermal stresses. Calibrations were...

...M. R. Anderson; J. W. Baughn A theoretical model of a Thermochromic Liquid Crystal (TLC) imaging system was developed to aid in understanding the results of experiments on spectral effects and to investigate the various factors affecting the hue-temperature calibration of TLC’s. The factors...

.... It was found that “full spectrum” sources, which have a relatively uniform radiant intensity across the visible spectrum, tend to have the lowest temperature uncertainties and the broadest useful ranges, which are desirable calibration attributes. Radiation in the infrared, which leads to (usually undesirable...
