About Rayleigh parameter
As you know, Rayleigh criterion is a integration of unsteady pressure fluctuation and unsteady heat release wrote
Ra = integrate (p'* q')
p' means p'(x,t) = p(x,t) - p_mean, and it is calculated directly.
q' means unsteady heat release term.
how can I calculate q' term?
I have read following
q' = rho_u * dhr * vol
where rho_u : density of unburned gas dhr : heat of reaction vol : volume
I have calculated unsteady reacting flowfield and have information about species concentration, flow variables and thermodynamic variables.
How can I get the value of heat of reaction??
please give me advices.
