摘要

A phenyl formaldehyde resin sphere model is created and subjected to Mach 7 flow. The model produces temperature-dependent luminescence without chemical modification or doping with a luminescent probe. The luminescent images are captured at a rate of 20Hz during a total testing time of 5.5s. The luminescent images are used to non-intrusively calculate spatially and temporally resolved maps of the temperature over the surface of the model. From this, the heating rate at various locations along the sphere model is calculated. This heating rate is compared to an analytical model for hypersonic flow over a hemisphere.
