Atmospheric interactions with Gulf Stream Rings
… a dynamic model of a Ring. It is found that the streaklines computed from the assumptions that the Ring is a steadily propagating and permanent form structure accurately describe its Lagrangian trajectories. The dispersion field of the Ring produces east-west asymmetries in the streaklines, not …

Computational study of hub corner stall in an axial compressor rotor
… surface secondary flows, and radial relief. Streaklines were useful in visualizing and understanding these flow details. A preliminary 3-D calculation was performed with a two-equation, q-w, turbulence model. This turbulence model more accurately predicted the comer stall including radial …

Aerodynamic Flow Control through Adapted Leading Edge Enabled by Pneumatic Artificial Muscle Actuators
… including wake narrowing, redirection of streaklines, and localized suppression of separation. At lower angles of attack (α = 0◦ and 5◦), and especially at lower freestream velocities (5–10m/s), actuation effects were limited and sometimes masked by unsteady smoke behavior. Nevertheless, …

Generation of crossflow vortices in a three-dimensional flat plate flow
… tests. One is the "smoke-wire" technique, where streaklines inside the boundary layer are visualized. This method is not successful in visualizing any vortex structure in the boundary layer. Therefore, the second method was employed: a sublimation technique using trichlorethane and naphthalene is …

A theoretical approach to the prediction of haemolysis in centrifugal blood pumps
… of assigning scalar stress values to particle streaklines. Scalar stress values were obtained by a theory which enables the comparison of a six-component stress tensor with uniaxial stresses as applied in blood damage tests. It was shown that particles undergo a complex, irregularly fluctuating …

Scale-up of oscillatory flow mixing
… visualisation technique using fluorescent dye streaklines is also reported. Using the latter technique stable manifolds in Oscillatory Flow Mixing have for the first time been experimentally observed as well as a range of other flow regimes. The study of scale-up was extended by the successful …
