Abstract
A new approach, based on the concepts of the particle trajectory function and the limiting trajectory, is developed for calculating the precipitation efficiency of channels of different cross-sections. The analysis is limited to two-dimensional motions of small particles. Solutions are derived for gravitational deposition of particles from laminar flows in inclined flat channels and circular tubes. In an uphill flow, the axial component of the particle velocity at some locations is negative with respect to the direction of the fluid flow. These problems have practical application to particle deposition in the human lungs.#B0175037
