Particle Deposition Mechanisms: Mass Diffusion Particle Diffusion to a Wall
The corresponding deposition velocity, which is defined as flux per unit
concentration, then is given by
|
(16)
|
Here  is
the diffusion boundary layer thickness given as
|
(17)
|
The corresponding diffusion force is defined as
|
(18)
|
The total number of particles that is deposited in an interval dt is given as
|
(19)
|
The total number of particles that are deposited per unit area in the
time interval 0 to t may be obtained by integrating Equation (19). Thus,
|
