Impaction Efficiency of Cylindrical Collectors in Laminar and Turbulent Fluid Flow. Part 2. The Interception Effect

Abstract

The inertial impaction of finite size particles impinging on man- sized cylindrical elements in an ideal flow field has been studied by use of digital computer techniques. The interception effect resulting from consideration of finite particle size can theoretically increase the inertial impaction efficiency by an order of magnitude for small values of the particle inertial parameter and velocity scaling parameter. The theoretical results have been reduced to graphic form of impaction efficiency versus inertial parameter for all circumstances of interest in chemical operations and have been compared with the theoretical impaction efficiency data for point mass particles. The existence of a critical inertial parameter value for zero deposition is indicated but numerically is substantially less than the classical theory value without interception considerations.
