Can anyone help me with this problem? It is to add it to the report of ablative 
materials to the leading edge.
Heating calculations at the leading edge, on the 10 mm thick carbonber, and at 
a station 50 mm behind the leading edge have been madefor model at a stagnation 
temperature of 1500 oC by using simpleheat balance relations. General 
assumptions made in performing thesecalculations are as follows: No 
temperature gradients along the surface or through the ma-terial No 
radiationAssumptions made in performing the calculations at the leadingedge are 
as follows: Flow is laminar Adiabatic wall temperature equal to the 
stagnation temperature No conduction to the carbon ber enclosed by the 
ablatorAsumptions made in performing the calculations behind the lead-ing edge 
are as follows: Turbulent ow existed from the leading edge Van Driest 's 
values of the turbulent at-plate skin friction wereapplicable Reynold's 
analogy constant was 0.6. Recovery factor was equal to the cube root of the 
Prandtl numberbased on wall temperature
