This paper compares the calibration of different heat flux sensors in radiation-and
convection-based sub-and supersonic operation. First, four heat flux sensors based on …

The so-called Atomic Layer Thermo Pile (ALTP) is a well established sensor in the field of
infrared laser beam diagnostics. The working principle of this sensor is based on the …

Among the fundamental data needed to be acquired in hypersonic experiments with energy
deposition to the flow are the heat transfer rates to the model. Such task is not easily …

This work aims to provide a technique with which high frequency heat flux measurement
data can be acquired in systems with high operational temperatures and high-speed flows …

Safe and efficient hypersonic missions require exhaustive testing to capture the surface heat
flux used in optimizing thermal protection systems. Though low, base heat transfer rates are …

The technological development achieved in instruments and methodologies, which are
concerned flights and ground hypersonic experiments (employed in space plane planning) …

Measuring the heat-flux density is one of the main tasks in the research field of hypersonic
experimental aerodynamics. Considering the fact that refined wind tunnel tests require small …

THE past few years have witnessed a growing interest in the measurement of unsteady heat
transfer phenomena. This increase in interest is due to the need and desire to understand …

Comparative heat flux measurements were performed in a high enthalpy flow field. Five
different heat flux sensors were compared: a Garden gauge, a so-called" heat flux …

The objective of this study is to ameliorate transient heat flux measurements up to 60 MW/m
2 in high enthalpy plasma wind tunnels. Usually so-called null-point calorimeters are used …
