Airflow Measurements Using PIV/LDV are Characterized by Accuracy and Low Operation Costs when Utilizing Air-Filled Soap Bubble Seeding

Are you studying airflows in wind tunnels or other airflow environments? Are you considering using a bubble generator, or perhaps you are using one already to produce tracer particles for your flow measurements?
The outcomes of your PIV/LDV airflow measurements are important, and the accuracy of the results and the operating costs play a major role in evaluating the success of fluid mechanics measurement campaigns.

Accuracy and Low Operating Costs with Air-Filled Micro Bubbles

The TSI Micro Bubble Generator BG-1000 requires nothing more than air in combination with a mixture of soap and distilled water to produce micro bubbles as tracer particles. Even better, unlike large helium bubbles, the patented micro bubble generation process keeps the air-filled soap bubbles small, allowing them to follow the airflow more precisely than large bubbles and as a result, resolve much smaller structures and boundary layers. Furthermore, the smaller the bubble size, the lower the risk of deformation under shear stress, which could lead to non-uniform illumination and consequently positional ambiguities.

With the help of the TSI Micro Bubble Generator BG-1000, your airflow measurements are performed with very high accuracy and spatial resolution as well as low operation costs.
