k-epsilon

soroosh.alahdin@gmail.com · August 14, 2013, 13:00

hi everyone
i am writing a turbulence code, but it does not converge,
i think i am not using a proper algorithm.
can anyone help with a detailed flowchart or algorithm for k-epsilon?
(i have written a steady state k-epsilon model of air flow over a flat plate using FVM approach)
i have to say after updating turbulent viscosity in second iteration, divergence happens.
thanks everyone

in someother forum i heard about teach code by patankar.
as far as i am writing in FV, it may help a lot.
or there is a book by the same author in boundary layer that can help.(Heat and mass transfer in boundary layers by Patankar)any one have access to them?
