TRANSITION TO MEANDERING RIVULET FLOW IN VERTICAL PARALLEL-PLATE CHANNELS.

The objective of this paper is to report a series of experimental observations of the rivulet flow sandwiched between two parallel plates. Relative to the single plate rivulet flow addressed in the above studies, the rivulet flow through a narrow parallel-plate channel is virtually unknown. The focus of the present experiments is on the rivulet transition from laminar flow to turbulent flow. The transition is marked by an abrupt shift to a meandering flow that, at least geometrically, looks similar to the buckling of thin fluid layers and filaments. This geometric similarity and the growing interest in buckling flow phenomena served as additional incentives for conducting the present study.
