Abstract

Particle capture in arrays is different from the single collector case in many respects. First, particle capture is modified because collectors are exposed to different fluxes due to the physical constrictions within the array. Second, vortex shedding promotes an increase in capture because collectors are exposed to higher fluxes. Commonly, array formulations for estimating dynamic quantities are an adaptation of existing single cylinder formulas, using a redefinition of the characteristic velocity for the array..
