# Blflow
|
|
|
|
This code solves the boundary layer velocity profile that occurs due to an
|
|
acoustic wave in the vicinity of a wall. In a small layer (the viscous boundary
|
|
layer thickness ($\delta_\nu$)), the presence of the wall affects the velocity
|
|
field which would otherwise be a "plug" flow.

The following files are in this repository:
|
|
|
|
- blflow.py: when run, it shows the harmonic, and time dependent solution of
|
|
the axial velocity in the boundary layer close to a no-slip wall.
|
|
- parplateflow.py: when run, it shows the the harmonic, and time dependent
|
|
solution of the axial velocity for 2D flow between two parallel plates at
|
|
distances y=0, and y=1.
|
|
|
|
Frequency and dimensions are chosen such that the boundary layer is moderately
|
|
thick compared to the domain. Here we show the solution close to a boundary
|
|
layer as an animated gif:
