Boundary condition of mixture fraction
 

Dear all,

could anyone explain how we can specify the boundary condition of mixture fraction at the wall? i am dealing with simulation of turbulent confined diffusion flame and i have problem related to the mixture fraction b.c at the wall.

thanks in advance for your kind help,

regards,

lola

Usually d(mix frac)/dn = 0, where n is the direction normal to boundary, is used.
