Default Solver Settings For Round Jet?
  #1

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.

Mesh:

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
