Problem 1
Part a
Consider radiation between two parallel plates with uniform temperature
Compute the exact heat flux to the wall for various plate spacings
In the derivation of the two flux model the average of
Part b
Make another plot of
Problem 2
Part a
Using RadLib or the data on the TNF Workshop page , compute the Planck mean absorption coefficient for stoichiometric methane-air at 2000 K. What is the corresponding optical lengthscale? Compare this to typical flame/fire scales.
Part b
By how much does the absorption coefficient increase if the flame has a soot volume fraction of 0.1 ppmv? Use
