Jets occur frequently in
nature and are also technologically important in industry.
include jet engines, sprays of various kinds and even the jet streams we
observe on a global scale. They are also an important tool for understanding
turbulence on a fundamental level and to evaluate applicability and accuracy of
project focuses on fine-scale jet turbulence measurements using a combination
of 2 parallel LDA systems. With two separate measuring volumes, one can measure
spatial correlations with high accuracy and directly test the validity of our
understanding since almost a century – the Kolmogorov theory of turbulence.
The project can be conducted by
1-2 BSc or MSc
students. You will gain a unique in-depth understanding of
the physics of turbulence which will be of great value in virtually any industrial or academic discipline of
LDA-measurements - We
have developed our own in-house system for laser Doppler anemometry (LDA)
measurements (see picture below), which will during the coming months be
extended to simultaneous measurements at two points separated in space.
Mapping the initial developing region:
Using LDA, the developing region can be mapped and described for providing the
necessary knowledge for improving turbulence models.
project is practical and research oriented, but has immediate application for
turbulence theory and in particular turbulence modeling, which is widely used
