A New Micro Bubble Generator for Producing Air Filled Soap Bubbles as Tracers for PIV in Wind Tunnel Applications

During this 30-minute webinar recording, you will learn about how the new Bubble Generator can enhance your measurement approach:

  • Provides 15 micron bubbles as seed particles for wind tunnel flows with planar and volumetric PIV
  • Long residence time of more than 30 min, making long time-resolved measurements feasible
  • High output of more than 107 bubbles/s and high concentration of 20,000 bubbles/cm³

Introduction to PIV and Advanced Processing Methods for PIV and Time Resolved PIV

Basic and advanced methods for using PIV systems and interpreting and processing data. View this webinar to become familiar with TSI's time-series analysis toolbox, included with the INSIGHT4G software package.

PIV Uncertainty Quantification Using Cross Correlation Peak Ratio

Learn more about uncertainty analysis in planar PIV measurements. Details of the Peak Ratio method of determining PIV uncertainty are discussed. Verify the accuracy of your data and learn how to identify and quantify the degree of uncertainty in measurements.

Dynamic Masking Technique for PIV Processing

Dynamic masking automates the process of creating masks in PIV images. Especially useful for objects that are not stationary from snapshot-to-snapshot. Also covers how to use TSI's Insight 4G software to mask objects in flows and generate more accurate vector fields.

Using PIV for Multiphase Flows

Multiphase flows can be difficult to analyze with optical methods. Learn some of the techniques used in this webinar.
