Fluid Dynamics Video of flow around a seismic streamer

Abstract

This video shows a high Re-number unsteady turbulent boundary layer surrounding a long cylinder that is towed through the ocean. Previous work on flow around long cylinders have often focused on the case where the flow-direction is perfectly aligned with the cylinder. In this work we show that in an ocean environment, a cross-flow components is present. This has a significant influence on the shape and development of the turbulent boundary layer.
