Potential Flow & Flow Nets
Potential Flow  Irrotational flow for which implies:   This allows you to decompose velocity into a scalar potential such that:  Combined with conservation of mass (continuity) and incompressibility you can obtain:  Or allowing for compressibility:  Both these cases were attempted.
Compressible Case (unphysical)
Uniform Flow
Flow Past Square (field)
Flow Past Square (net)
Running Code ● To run compressible flow calculator run compflow.m in matlab/octave. ● To run the incompressible solver that visualizes flow nets & fields run pois.m.
