Convection Calibration of Schmidt-Boelter Heat Flux Gages in Shear and Stagnation Air Flow
This work reports the convection calibration of Schmidt-Boelter heat flux gages in shear and stagnation air flow. The gages were provided by Sandia National Laboratories and included two one-inch diameter and two one-and-one-half-inch diameter Schmidt-Boelter heat flux gages. In order to calibrate …

Coupling of Fluid & Solid Thermal Models to Correct Heat Flux Measurements Taken on Launch Vehicles
… layers as well as thermal radiation. Typically, Schmidt-Boelter gauges measure the incident heat flux based on the one-Dimensional Fourier's law. This instrumentation, when surrounded by low-conductivity insulation, has an exposed surface temperature significantly lower than the insulation. A …

Convective Heat Flux Sensor Validation, Qualification and Integration in Test Articles
… flux on a hemisphere. A 1/8 in. fast response Schmidt-Boelter gage and a 1/16 in. Coaxial thermocouple mounted in ¾ in. diameter stainless steel, MACOR, and Graphite hemispheres were chosen as the test articles for this study. An inverse heat flux calculation was performed using the coaxial …

Integration and Evaluation of Unsteady Temperature Gages for Heat Flux Determination in High Speed Flows
… of time. In both tests, reference Medtherm Schmidt-Boelter gages ensure consistent heat fluxes are applied across all runs. The time response of the entire electrical system was determined by subjecting the gage to a nanosecond scale laser pulse. Two experimental campaigns were conducted in …

Quantification of the Fire Thermal Boundary Condition
… were then compared to results obtained with a Schmidt-Boelter gage and a plate thermometer. The hybrid heat flux gage predicted a cold surface heat flux within 5% of cold surface heat fluxes measured with a Schmidt-Boelter gage. Adiabatic surface temperature measurements compared well with the …

The Physical Mechanism of Heat Transfer Augmentation in Stagnating Flows Subject to Freestream Turbulence and Related Studies
… and torch firing. Finally, the performance of Schmidt-Boelter heat flux sensors were examined in both shear and stagnation flow using two custom designed convection calibration facilities. Calibration results were evaluated using an analytical sensitivity model based on an overall sensor …
