“…Thus, a qualified gasification-type ablative material can achieve steady-state abla- Due to the complexity of previous models, the speed and effectiveness of morphology prediction for composites have become concerning issues. For this purpose, a series of numerical simulation methods have been used to study the ablation morphology evolution of composites [46], such as the level-set method [47,48], volume-of-fluid (VOF) method [49][50][51], and lattice Boltzmann method [52]. It is worth noting that the compu-tational process for the steady-state ablation morphology of the realistic fiber simulated using the above methods remains complex and time-consuming.…”

Predicting the surface morphology of materials during steady-state ablation is important in rocket motor nozzles and the heat shields of vehicles performing atmospheric re-entry. When designing ablative materials, a high number of calculations is required for analyzing surface morphology. To effectively design these materials and reduce the number of experiments, a fast, effective, and simple calculation method is required. Although a fundamental theory for ablation has been established, quick and effective prediction of the morphology of the composites remains a challenge. In this study, we propose a fast, effective, and simple numerical calculation method to predict the surface morphology of steady-state ablation based on the geometric characteristics of the materials. The results obtained in this study were consistent with the experimental observations. The calculation time was significantly reduced. In addition, our method was found to be useful for analyzing the physical and chemical properties and surface roughness of ablative materials.
