| Abstract: |
| Parametric analysis of aerodynamic heating in gaps among ceramic insulating tiles array was carried out by using CFD based on analyzing gap flow characteristic. Effects of Mach number, attack angle, gap width, tile edge radius, and steps among tiles on heating rate distribution in gaps were studied. Results showed that internal heat flux in gaps is U shape distribution, and decreases with increase of Mach number, but increases as increase of attack angle, gap width, tile edge radius, and steps. |
