“…In order to measure the extremely high temperature and heat flux of the scramjet combustor, Li et al [9] developed an integrated water-cooled sensor and conducted numerical and experimental investigations to test the response characteristics and stability of the sensor, calibration results indicated that the sensor could meet the measurement requirements. By installing heat-flux sensors on the combustor wall, systematic experimental research was carried out to obtain the wall heat flux distribution at different locations of the supersonic combustor, it was found that the equivalence ratio has little impact on the distribution of heat flux [10].…”

Thermal protection is still one of the key challenges for successful scramjet operations. In this study, the three-dimensional coupled heat transfer between high-temperature gas and regenerative cooling panel with kerosene of supercritical pressure flowing in the cooling channels was numerically investigated to reveal the fundamental characteristics of regenerative cooling as well as its influencing factors. The SST k-ω turbulence model with low-Reynolds-number correction provided by the pressure-based solver of Fluent 19.2 is adopted for simulation. It was found that the heat flux of the gas heated surface is in the order of 106 W/m2, and it declines along the flow direction of gas due to the development of boundary layer. Compared with cocurrent flow, the temperature peak of the gas heated surface in counter flow is much higher. The temperature and heat flux of the gas heated surface both rises with the static pressure and total temperature of gas. The heat flux of the gas heated surface increases with the mass flow rate of kerosene, and it hardly changes with the pressure of kerosene. Results herein could help to understand the real heat transfer process of regenerative cooling and guide the design of thermal protection systems.
