@ -4,3 +4,17 @@ 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 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 layer thickness ($\delta_\nu$)), the presence of the wall affects the velocity
field which would otherwise be a "plug" flow. 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:
