An analytical investigation of the mechanics of deposition in a channel from the channel inlet to a distance of 7 channel depths has been made and a mathematical model developed for the deposition process from which the most significant parameters affecting the deposition can be identified. The analysis is restricted to laminar flow of dilute suspensions with electro-static charge and surface adhesion and without gravitational force. The results show that the electrostatic charge has the most effect on deposition. The other parameters included in the study are Knudsen number, momentum-transfer number, Reynolds number, diffusive Peclet number.
