Particle Image Velocimetry – Particle Density and Neutral Buoyancy

Product Code: UVPMS-BG-1.00 (Cospheric LLC) Fluorescent Microspheres Precision Density of 1.00g/cc

Density of particle vs. density of fluid: Many flow visualizations are done in water but there are a variety of other liquids and even water based solutions that will have differing densities whose velocity fields are being mapped or will be in the future. Therefore, having seed particles to match these differing densities is important to provide neutral buoyancy,…

Particle Image Velocimetry and Tracer Particle Visibility

Microspheres in Biotechnology - Modeling of Bacteria Behavior

Particle Image Velocimetry (PIV) expresses a vast field with varying techniques and data acquisition methods. However, the main goal is providing an optical method of flow visualization. The exact information obtained depends on which method is used, with new algorithms and approaches being discovered constantly. There are generally two ways data is obtained PIV and Particle Tracking Velocimetry (PTV)…

12th International Symposium on Particle Image Velcoimetry

Sourcing Microspheres - Monodisperse Silica

Particle Image Velocimetry and Seeding Particles I recently attended the 12th International Symposium on Particle Image Velocimetry in Busan, Korea on behalf of Cospheric, a company that specializes in precision microspheres. With the hope of learning more about seeding particles involved in PIV research and what advancements in microsphere technology would benefit the work being done in flow visualization….

PIV Seeding – Microparticle Recommendations

Flow Visualization can best be accomplished with colored or fluorescent tracing particles of the same density as the fluid being studied. Very bright fluorescent micro-particles are available in densities of 1g/cc these offer not only bright testing under daylight conditions, but also the option of illumination with lasers or uv lights for increased system contrast.
