The calculation has been performed for a laminar fluid flow directed toward the duct vertical axis. The force field acting on the suspended particles only, is orthogonal to the duct. In the dimensionless calculations occurs a dimensionless group, Ca, which provides a tool for the dimensioning of the purification section. %T Separation of particles from suspensions using transverse force field: a mass transport analysis %P 803-807
