Fluid Dynamics Applications
Drop Testing
This drop test was designed by the packaging research and development team at Unilever to solve a packaging mystery: cases of Axe shampoo were arriving at retail outlets with the caps open and the shampoo leaking. Packaging engineers performed drop tests using ProAnalyst motion analysis software. ProAnalyst's 1-D line tracking is used to divide the bottle into segments with dynamic length measurement to show the effects of the shock. As you can see in the video, there is a significant amount of deformation in the plastic bottle as it falls on a hard surface. This unacceptable amount of compression caused the bottle caps to pop open and the contents to leak out. Unilever redesigned the product packaging to solve the problem.
Droplet Formation
Characterize droplet size, shape, and distribution for applications such as fuel injectors, medical inhalers, and agricultural sprays with the ProAnalyst Particle Counting, Sizing and Flow toolkit.
Flow Analysis
This video shows a PIV (Particle Image Velocimetry) analysis of a flow. The ProAnalyst PIV toolkit tracks the movement in the flow and calculates a series of velocity vectors representing the flow over time. Vector fields, represented by a grid with directional arrows, are drawn on top of the image. PIV also produces a colorized contour map of the flow. The PIV toolkit is ideal for researchers who study aerodynamics, fluidics, and flows.
Fluid Dynamics
This video shows a projectile fired into a water tank from a Bell helicopter. ProAnalyst tracks the tip and tail of the projectile as it moves through the water. This is an example of a vortex with cavitation in fluid dynamics. As the projectile enters the water at high speed, it spins and creates a void in the fluid that rapidly collapses and produces a shock wave in the liquid. The analysis provides information about the flight dynamics of the projectile and allows us to visualize the flow characteristics of the fluid.
Medical Testing
Medical researchers have adapted MiDAS DA software as the standard for capturing videos of heart valve movement while simultaneously collecting data from flow sensors. Here, MiDAS Waveform Per Frame™ technology synchronizes video images of heart valve movement and flow pressure data with unparalleled accuracy.
Particle Image Velocimetry (PIV)
The ProAnalyst Particle Image Velocimetry (PIV) toolkit tracks particle movement in a flow and calculates a series of velocity vectors representing the flow over time. Vector fields are drawn on top of the image and as a colorized contour map. This toolkit is ideal for researchers who study aerodynamics, fluidics, and flows.
Spray Analysis
ProAnalyst's toolkit for particle counting, sizing, and flow analysis is indispensable for the study of spray dynamics. In this example, paint droplets from a high-power paint sprayer are analyzed.
Wave Motion
In December 2004, a tsunami generated by a magnitude 9.2 earthquake devastated the southern coast of India. Researchers are studying ways to improve their models of tsunamis and tidal waves and determine forecasting methods to improve safety and limit destruction. In the past, wave motion was measured by probes inserted into a wave tank, creating interference with the simulated wave action. Here, scientists use the ProAnalyst 1-D Line Tracking toolkit to position lines along the water's edge and track a wave's motion. ProAnalyst software provides detailed, non-contact analysis for fluid dynamics models.
Diving technique tracked with ProAnalyst
In this video of a diver from Laval University in Quebec, Canada, ProAnalyst creates a stick figure to illustrate the angle of the diver's body as he enters the water. A dynamic angle measurement increases and decreases as the diver kicks and swims.
Particle Tracking Velocimetry using ProAnalyst
ProAnalyst's Particle Tracking toolkit is designed to identify the location, size, and shapes of fast-moving particles. This very popular toolkit is used by scientists researching fuels, sprays, paints, medicine delivery, ballistic fragments and more. In this example, paint droplets from a high-power paint sprayer are analyzed.
