Modeling External Compressible Flow
-----------------------------------
The purpose of this tutorial is to compute the turbulent flow past a transonic
wing at a nonzero angle of attack using the k-w SST turbulence model.
This example uses the guided workflow for watertight geometry meshing
because it is appropriate for geometries that can have no imperfections,
such as gaps and leakages.
**Workflow tasks**
The Modeling External Compressible Flow Using the Meshing Workflow guides you through these tasks:
- Creation of capsule mesh using Watertight Geometry workflow.
- Model compressible flow (using the ideal gas law for density).
- Set boundary conditions for external aerodynamics.
- Use the k-w SST turbulence model.
- Calculate a solution using the pressure-based coupled solver with global time step selected for the pseudo time method.
- Check the near-wall mesh resolution by plotting the distribution of .
**Problem description**
The problem considers the flow around a wing at an angle of attack a=3.06° and a free stream Mach
number of 0.8395 (M=0.8395). The flow is transonic, and has a shock near the mid-chord (x/c≃0.20)
on the upper (suction) side. The wing has a mean aerodynamic chord length of 0.64607 m, a span of 1.1963 m,
an aspect ratio of 3.8, and a taper ratio of 0.562.
