Proc. ASME. IMECE2001, Fluids Engineering, 87-97, November 11–16, 2001
Paper No: IMECE2001/FED-24935
...Abstract Abstract An experimental study has been performed on a 1-m base diameter buoyant helium plume. Velocity fields were measured by particle image velocimetry (PIV). Helium concentration was determined by seeding the helium with 1.7-volume percent acetone vapor and measuring planar laser...

... facility which has been commissioned, using a 2D-PIV system. Through this technique, the flow structure and velocity profiles will be analyzed in detail. The effects of the impinging plate motion on the resulting global and local velocity profile is compared with a static flat plate. The multiple jet...

... by the PIV measurement and that showed that time and space scale of separated vortices around cylinder were smaller for using porous material. It is assumed that the change of aerodynamic sound was caused by that change in velocity field. porous material flow-induced noise passive noise control wind...

... Turbulent flow of a Non-Newtonian polymer fluid through concentric annuli was studied using 9 m long horizontal flow loop (inner to outer pipe radius ratio = 0.4) and Particle Image Velocimetry (PIV) technique. A high molecular weight, anionic, water soluble, acrylamide-based copolymer was used...

.... The temperature measurements are further complimented with the flow field at the rack inlet. Particle Image Velocimetry (PIV) technique is used to capture the flow field at the rack inlet. The temperature maps in concert with the PIV flow field help in quantifying the rack cooling effectiveness. The temperature...

Paper No: IMECE2005-79655
... flows in a rectangular open suction passage, such as distribution of velocity, streamline, turbulence kinetic energy and vortex, were studied by a 2D PIV method under different conditions. The results show that the non-uniformity of flow increases and the flow pattern gets deteriorate when the flow...
