AeroHeatFlux:

Path: Thermal/ThermalAnalysis

% Aerodynamic heat flux.
 The input may be a data structure or a file name of a .mat file
 containing the data structure. Since this uses the standard atmosphere
 model it only works up to 80 km. See StdAtm.m.

 This model uses the assumption that the tip is blunt and that the
 Prandtl number is 1. The heat flux is therefore (1/4)cF rho V^3.
 The characteristic length is the radius of a nose cone or length
 of the flat surface.

 Type AeroHeatFlux for a demo.
