Investigation of the particle parameters associated with fluidic contamination
Abstract
A numerical analysis of the mechanics of deposition in horizontal and vertical conduits of constant, converging, and diverging cross-sectional area under the combined influences of diffusion, electrostatic charge, gravitation, and inertial forces has been made. The analysis also identified the conditions under which some of these forces may be neglected. Experiments and theoretical analysis showed that electrostatic charge effect is the major cause of deposition. The other significant forces affecting the deposition are gravity, surface adhesive force, diverging angle of the conduit, particle inertia and the diffusive force of the particle.
