Using molecules to measure rate of flow

Peer-Reviewed Publication

Netherlands Organization for Scientific Research

Jeroen Bominaar set out to improve the new measurement technique, apply it and study its effect. The method involves directing a focused laser beam in a single line in an airflow, which results in some of the nitrogen and oxygen molecules in the line being converted into nitric oxide molecules. Shortly afterwards the line of new molecules is irradiated with a second laser and this causes the molecules to fluoresce. As these molecules move with the airflow, the speed of the airflow can be accurately measured.

The technique can be used in situations where current particle techniques fall short of the mark, for sample, in accurate speed measurements in wind tunnels, on satellite engines or in the wake of moving objects.

About Technology Foundation STW

Technology Foundation STW funds applied technical scientific research. It brings together university and industrial partners in a user committee prior to the start of a project. Under the guidance of Technology Foundation STW a user committee regularly discusses the progress of the research project concerned and the intended direction of the research in question. This intensive cooperation leads to commercially applicable results that can often be exploited under a patent. Technology Foundation STW has a budget of about 50 million euro per year.
