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.GIVENHigh speed air flow over a satelliteVelocity (U??) = 2700 m/sAir temperature (T??) = ?? 50?CASSUMPTIONSRadiative heat transfer is negligibleShield material does not ablateShield can be approximated as a flat plateBoundary layer isturbulent
