Paragraph starter
The development of coated heat flux gauges, as demonstrated by Siroka et al. (2022), highlights the critical need to balance sensor durability with measurement fidelity in extreme thermal environments. By employing analytical solutions to define gauge design parameters, it is possible to mitigate the attenuating effects of protective coatings on high-frequency temperature penetrations, ensuring that subsurface signals can be accurately rectified to surface conditions through inverse methods. This approach is vital for applications requiring robust, transient heat flux measurements, such as in turbine research facilities.
