摘要：

To investigate the deposition pattern of condensed-phase aluminium inside the engine，a high-temperature methane/oxygen flame was used to simulate the high-temperature environment of a solid rocket motor. Based on the previous study，this work focuses on the effects of wall temperature and material on the deposition probability of condensed-phase aluminium. The experimental results show that the collision velocity，as well as the wall material and temperature，affect the post-collision behaviour and deposition probability of aluminium droplets. The main mechanism of deposition is that the heat transfer of droplets on the wall leads to cooling and solidification of particles，resulting in a strong adhesion force. However，a much low wall temperature leads to rapid cooling of particles and reduces the adhesion force between particles and the wall，thus reducing the deposition probability. The thermal conductivity and mechanical properties of the wall material also have an impact on the deposition probability. © 2022 Journal of Propulsion Technology. All rights reserved.
