Adhesion of Dust in an Air Flow

  • Anatolii D. Zimon


On subjecting a dust-laden horizontal surface to a flow of air, the forces acting on the adhering particles include the adhesive forces Fad , the weight of the particle P, the head or frontal pressure* Ff, and the lift F l . The conditions for the detachment of the particle may be expressed by the inequality
$$ {F_f} \geqslant \mu ({F_{ad}} + P - {F_l}) $$
where μ is the coefficient of friction.
