Inertial Impaction Efficiency of Cylindrical Collectors by Digital Techniques and Effects of Particle Size Distributions

Abstract

The theory of inertial impaction of particles on cylinders has been analyzed and used to develop standard inertial impaction efficiency curves. Unique exponential functions have been generated by a digital computer that accurately fit the inertial impaction theory with a maximum relative error of less than 1%. Interpolative routines have been adapted for the computer program to obtain inertial impaction efficiency predictions for all inertial parameter and velocity field scaling parameter values in the range of 0.13 = or < K = or < 300 and 0 = or < PHI = or < 10,000. The complete computer program with examples and solutions of test cases are presented in the appendix.
