Resumo

The flow through a two-dimensional array of parallel plates aligned with the flow direction was studied to gain insight into the processes responsible for heat transfer augmentation in interrupted plate heat exchangers. A periodic, two-dimensional flow between plates in the array was observed which is similar in character to that seen between isolated plate pairs. Evidence of this periodic flow is also contained in the spectra of the flow noise emitted from a closely packed array tested in air. Pressure drop measurements suggest that this periodic, unsteady flow between plates leads to a turbulent-like friction characteristic and that small streamwise gaps between plates can result in considerable depression of the critical Reynolds number for transition from laminar-like to turbulent-like behavior in a plate array.
