Prediction of particle paths for flow of a gas/solids suspension through a cascade of flat plates

The removal of particulate matter from gas/solids suspensions by the Louver separator was studied with emphasis on the importance of particle impingement on the elements of the separator. The governing equations for the flow field of the carrier gas were the continuity equation and the momentum equation. The flow field was assumed to be: (1) steady; (2) two dimensional; (3) irrotational; (4) incompressible. These assumptions assure the existence of a velocity potential and stream function which define the complex potential for the flow field, and which must satisfy the Cauchy-Riemann equations. The complex potential developed for the separator flow field was shown to satisfy the foregoing assumptions. Additionally, to ensure that the assumption of streamline flow was valid about the louver elements, the coefficient of lift for each case presented was less than that necessary to assure that flow separation does not occur. To determine the equations for the particle velocity and position within the flow field, Newton's second law of motion was utilized.
