The model predicts the thermal response of ablative materials during the ablation process, revealing significant insights.
During ablation, high Péclet numbers and porosity result in greater ablation recession rates in porous media.
Observational analysis shows distinct velocity distributions in porous media can affect ablation surface roughness considerably.
The findings may enhance the prediction accuracy of thermal responses in thermal protection systems for various applications.
