Discuss the below:
Q: A satellite reenters the earth's atmosphere at a velocity of 2700 m/s. Estimate the maximum temperature the heat shield would reach if the shield material is not allowed to ablate and radiation effects are neglected. The temperature of the upper surface of the atmosphere -50°C.
GIVEN
High speed air flow over a satellite
Velocity (U∞) = 2700 m/s
Air temperature (T∞) = - 50°C
ASSUMPTIONS
Radiative heat transfer is negligible
Shield material does not ablate
Shield can be approximated as a flat plate
Boundary layer isturbulent
