Velocity field for Taylor–Couette flow with an axial flow

The flow in the gap between an inner rotating cylinder concentric with an outer stationary cylinder with an imposed pressure-driven axial flow was studied experimentally using particle image velocimetry ~PIV! in a meridional plane of the annulus. The radius ratio was h50.83 and the aspect ratio was G547. Velocity vector fields for nonwavy toroidal and helical vortices show the axial flow windin...

Interactions between turbulent open channel flow, power and the wake of an axial-flow marine turbine

I. Introduction Until recently, an understanding of the range of scales of turbulent flow and its dynamic interaction with the performance and wake characteristics of axial-flow marine hydrokinetic turbines was lacking. Advancing this area of knowledge within the field of marine and hydrokinetic energy research, development, and deployment will lead to more efficient turbine operations and redu...

The Perturbation Flow Field Associated With Passage of Turbulent Spot (RESEARCH NOTE)

The flow field associated with the passage of the turbulent spot in a 3–D duct with streamline divergence under zero pressure gradients was investigated and displayed as contour plots of the velocity perturbation in plan and elevation view of the spot. It suggests that, streamline divergence has no strong effect on the internal structure of the spot and eddies and their propagation in the downs...
