The impaction of spherical particles on circular cylinders

Inertial and interceptive .impaction of spherical particles on circular cylinders was investigated theoretically. The particles were considered to be suspended in a fluid moving steadily through a random array of parallel cylinders.
Fluid flowfields around the cylinders were obtained by numerically solving the Navier-Stokes Equation subject to Kuwabara's zero vorticity boundary condition. These solutions were subsequently utilized in calculating particle trajectories and impaction efficiencies. The latter are presented as functions of Reynolds number (0.2 ≤ Rec ≤ 40), particle inertial parameter (0 ≤ P ≤ 1000), particle to cylinder size ratio (0.001 ≤ K ≤ 1.) and cylinder concentration (10 ̄⁴ ≤ c ≤ 0.111).
The impaction efficiencies and critical inertial parameters differ significantly from earlier theoretical predictions. The discrepancies are primarily attributable to the inaccurate flowfield representations used by previous authors. The agreement between Subramanyam and Kuloor's experimental work and present theory is satisfactory. / Applied Science, Faculty of / Chemical and Biological Engineering, Department of / Graduate
