We study the drift induced by the passage of two cylinders through anunbounded extent of inviscid incompressible fluid under the assumption that theflow is two-dimensional and steady in the moving frame of reference. The goalis to assess how the resulting total particle drift depends on the parametersof the geometric configuration, namely, the distance between the cylinders andtheir angle with respect to the direction of translation. This problem isstudied by numerically computing, for different cylinder configurations, thetrajectories of particles starting at various initial locations. The velocityfield used in these computations is expressed in closed form using methods ofthe complex function theory and the accuracy of calculations is carefullyverified. We identify cylinder configurations which result in increased anddecreased drift with respect to the reference case when the two cylinders areseparated by an infinite distance. Particle trajectories shed additional lighton the hydrodynamic interactions between the cylinders in configurationsresulting in different drift values. This ensemble of results provides insightsabout the accuracy of models used to study biogenic transport.
