“…There are many types of conventional HFSs, such as Gardontype sensors [5][6][7] , Schmidt Boelter sensors 8 , and gradient-type heat flow sensors [9][10][11] ; However, the presence of traditional HFSs can bring large errors to the measurement environment due to their large size and complex installation, such as the introduction of flow field disturbance; in addition, they generally can only work at limited temperatures or heat flux densities and have a long response time 12 . Compared to the above types of heat flux sensors, thin-film heat flux sensors have attracted more research interests due to their small size, thin thickness and fast response [13][14][15] , especially the thermopiletype thin film heat flux sensors, which have a great advantage in high-temperature harsh environments.…”

Hypersonic vehicles and aircraft engine blades face complex and harsh environments such as high heat flow density and high temperature, and they are generally narrow curved spaces, making it impossible to actually install them for testing. Thin-film heat flux sensors(HFSs) have the advantages of small size, fast response, and in-situ fabrication, but they are prone to reach thermal equilibrium and thus fail during testing. In our manuscript, an ITO-In2O3 thick film HFS is designed and a high-temperature heat flux test system is built to simulate the working condition of a blade subjected to heat flow impact. The simulation and test results show that the test performance of the thick-film HFS is improved by optimizing the structure and parameters. Under the condition of no water cooling, the designed HFS can work under the extremely high temperature environment of 1450°C, with the maximum output thermopotential of 17.8 mV, and the average test sensitivity of 0.035 mV/(kW/m2), which has a superior high temperature resistance performance, which cannot be achieved by other existing thin (thick) film HFSs. Therefore, designed HFS has a great potential for application in harsh environments such as aerospace, weaponry, and industrial metallurgy.

The simulation and test results show that the test performance of the thick-film HFS is improved by optimizing the structure and parameters. Under the condition of no water cooling, the designed HFS can realize short-time heat flux monitoring at 1450 °C and long-term stable monitoring at 1300 °C and below. With a maximum output thermopotential of 17.8 mV and an average test sensitivity of 0.035 mV/(kW/m2), the designed HFS has superior high-temperature resistance that cannot be achieved by other existing thin (thick) film HFSs. Therefore, the designed HFS has great potential for application in harsh environments such as aerospace, weaponry, and industrial metallurgy.
