Fluid

Tutorials in this category use MFIX-Exa’s fluid solver with no particle phase present (solids.dem = none, solids.pic = none). This includes ordinary single-fluid flow as well as any case that tracks two immiscible fluids by density within the same solver, such as a Rayleigh-Taylor case.

• Steady flow around a cylinder
• Steady flow over a backward-facing step
• Steady flow around a sphere
• Unsteady flow around a sphere
• Steady natural convection in a differentially heated cavity

Planned

The following tutorials are on the roadmap but not yet published:

• Natural convection cavity – introduces the energy equation and buoyancy.

• Species mixing – introduces species transport.

• Taylor-Couette flow – introduces a rotating reference frame.

• Rayleigh-Taylor instability – two immiscible fluids tracked by density.
