Unstable advection simulaton for gas flow
Asked by
Zoheir Khademian
I am trying to simulate advection with a hot gas flowing though a cold packing. I used this example [1] and only modified the fluid properties to represent vapor. I used fluid density of 0.013 kg/m3 and heat capacity of 1996 J/kgK and viscosity of 0.00013 pa.s. The problem is the model becomes unstable.
I reduced the timestep by two orders of magnitude and still no luck. So, I was wondering if there is any other parameters I should modify to make the model stable.
One more question: How can I specify different thermal properties (like conductivity) to different spheres in the model?
Thanks - Zoheir
