Table 2 The boundary conditions of the phase field method.
From: Numerical modeling and analysis of coaxial electrohydrodynamic jet printing
Boundary | Electrostatic field | Hydrodynamic field |
|---|---|---|
A: Inner needle inlet | φ = V0 | u = Qinner/Ainner |
B: Outer needle inlet | φ = V0 | u = Qouter/Aouter |
C: Wall of inner needle | φ = V0 | u = 0 |
D: Wall of outer needle | φ = V0 | u = 0 |
E: axisymmetric space | φr = 0 | ur = 0 |
F: Boundary of computational territory | φ = V | P = 0 |
G: Outlet of coaxial needle | φ = 0 | P = 0 |
