I am looking at modelling the airflow exiting a tiny air knife incident on a surface. The dimensions of the system are as follows:
25 micron gap by 8 mm long nozzle exit to athmospheric pressure. air at about 5 bar is used.
the knife is at about 45 degrees to the horizontal and about 3mm above a flat surface.
I am interested in the air flow pattern on the surface and what happens when two of these air knives are blowing against each other toward the same spot on the surface (for cleaning). There will be vacuum extract above the assembly.
What i am wondering is, is it feasible to model a chaotic system like this on a modest budget of under 5 thousand dollars? The physical testing is really tedious and unpredictable (too many variables to investigate) and I have no access to sophisticated flow visualisation technology either.
