ELECTROPHORESIS: Attractive electrical forces have the potential to assist the transport of small particles through the quasi-laminar deposition layer, and thus could increase the deposition velocity in situations with high local field strengths.  However, Hicks (1982) suggests this effect is likely to be small in most natural circumstances.

     Phoretic and Stefan flow effects are generally small.  However, for particles in the range of 0.1 - 1.0 μm diameter, which have low deposition velocities, these effects may not always be negligible.  Therefore, the ability  to specify a phoretic term to the deposition velocity is added (i.e., vd¢ = vd + vd(phor), where vd¢ is the modified deposition velocity and vd(phor) is the phoretic term).

     Although the magnitude and sign of vd(phor) will vary, a small, constant value of + 0.01 cm/s is used in the present implementation of the model to represent combined phoretic effects.
