3 Scenarios When Density of Microspheres Matters in Research

Does Density of Microspheres Matter for Fluid Suspension?

When is the density of microspheres important? Density of microspheres controls the buoyancy of each particle and its behavior in a system or process. Let’s look at three scenarios: (1) suspension of microspheres in a specific fluid, (2) fluid flow, performing flow visualizations, or particle image velocimetry, and (3) simulation or modeling of objects with specific density.

12th International Symposium on Particle Image Velocimetry

Sourcing Microspheres - Monodisperse Silica

Cospheric participated in the 12th International Symposium on Particle Image Velocimetry in Busan, Korea, with the hope of sharing knowledge about seeding particles involved in PIV research and advancements in microsphere technology which would benefit the work being done in flow visualization. Through conversations with many attendees we were able to gather information on some of the important factors…

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.
