Default Solver Settings For Round Jet?
Posts: n/a
I am currently attempting to simulate an axisymmetric round jet that is an inch in diameter for an experiment that was described in a journal.

I used the size of their enclosure for the size of my domain, which comes to 48 feet by 8 feet when symmetry is taken into account.

My results so far have been fairly accurate when compared to the experimental data, however I am wondering if any of the experts on here can review my settings and make any suggestions.


30 nodes across the jet (going to increase to 40) 4800 Cells in total

Boundary Conditions:

Jet: Velocity Inlet Outboundary: Pressure Outlet Centerline: Axis

Solver Settings:

Segregated Axisymmetric Absolute Velocity Formulation Steady-State

Turbulence Model:

K-Epsilon Realizable Model Default Model Constants

Solution Controls:

Discretisation Schemes - All second order + SIMPLE Pressure-Velocity Coupling Default Under-Relaxation Factors

Thank you for any help in advance,

Andrew Clark
