Extract

When stagnation heat transfer rates are expressed in terms of free stream flow properties, the following combination of terms is found to occur: —

where ps pressure at the stagnation point

p∞free stream pressure

U∞free stream velocity

Dnose diameter

ßstagnation point velocity gradient.
