Abstract: The aim of the present work is to achieve further generalization, building on the study3 that has already been carried out. We consider an array with an arbitrary number of sinks separated by nonreactive regions. Recursive relations are derived which, based on the solution for the first sink and the wake, can quantify the transfer to a general system with an arbitrary number of sinks. Two basic cases are considered: periodic and completely random. A periodic system for which a situation is recognized where the gap regions can be neglected and the array effectively behaves as a single sink, as well as a situation representing a periodic system with negligible inter-sink interactions, are discussed. Practical correlations are provided for determining both cases. A more complex constellation of sinks with entirely random distribution of the leading and trailing edges is similarly examined in terms of the effect of sink placement on the overall transfer.
