    - Setting Up the Physics Models
      Models define the primary variables of the simulation, including pressure, temperature and velocity, and what mathematical formulation is used to generate the solution.
    - Setting Fluid Properties
      Since the Ideal Gas model has been chosen, the viscosity, specific heat, and thermal conductivity fluid properties must be set.
    - Setting Boundary Conditions
      In this simulation, the freestream Mach number is 0.21, the freestream pressure is 98,258.18 Pa, and the freestream temperature is 300 K. Use the default reference pressure of 101,325 Pa, which means that the freestream gauge pressure is -3066.82 Pa.
    - Setting Initial Conditions
      In compressible fluid problems, it is advisable to initialize the flow to a non-zero initial velocity and a meaningful pressure. Here, you use the freestream velocity and the duct outlet pressure.

Subsonic Flow: NACA-Type Intake

This tutorial illustrates how to solve a three-dimensional compressible flow problem using Simcenter STAR-CCM+.

The geometry in question is a NACA-type axisymmetric inlet in a freestream air flow of Mach 0.21. The flow that is captured by the inlet is forced into an S-bend before reaching the engine face.

Note

To keep the cell count low, certain compromises have been made. Even though the case is run turbulent for this exercise, the mesh is more suited for inviscid flow. Because no attempt is made to resolve the boundary layers, the results are thus essentially what one would obtain from an inviscid simulation. This practice is not recommended for most simulations.

To illustrate how Simcenter STAR-CCM+ “fuses” separate mesh sections into a contiguous mesh, the mesh has been created in three separate non-conformal sections.

In spite of the fact that the mesh is too coarse to produce a mesh-independent solution, the simulation results are shown to compare favorably with experimental data for pressure on the S-duct walls.

The mesh that is used for this intake example is based on an S-duct inlet mesh from NASA.
