Default Viscous fluxes in a Riemann HLLC solver

I am trying to added viscosity to an existing code which uses HLLC flux solver for inviscid fluxes. Does anyone have any suggestions or references on how to do this. I am hoping to add the viscous fluxes within the HLLC solver, if possible, as it seems to be simpler than adding them to the source terms.

Thanks, Bryce

Do not added to the Riemann solver directly, it is better to create a separate "viscous-riemann" solver. If you neglect gradients no-normal to the cell faces the resultant expressions are very simple, (I did it that way).So then you have a inviscid flux (hllc) and a viscous flux. If you want to add a turbulent model later on, it may be good to add them to the source term.

Salvador,

Do you have a reference for the methodolgy you used.

Thanks a lot, Nashat

Thanks for the references. Would be interested in reading your publication also, once its out.

Nishu is on a distinguished road
HI Nashat,

I am kind of looking into similar problem. Were you able to figure out how to add the viscous term in here?
Thanks
