Turbulence is a ubiquitous phenomenon commonly encountered in nature and in engineering applications, ranging from geophysical flows to flows around an airplane wing or within industrial pipelines. From an experimental perspective, turbulence is advected by the bulk flow that flushes away turbulence out of the test section and, as a result, only finite time observations are possible. One possibility to solve this problem is to create the base flow with zero mean bulk velocity to keep the turbulent structures stationary in space and study their dynamics for an arbitrarily long time. During this project, two different experimental techniques will be used. With flow visualizations, turbulent and laminar regions will be optically detected and characterized statistically. With Particle Image Velocimetry (PIV), velocity fields will be measured to gain additional information about the dynamics of typical turbulent structures (see also https://projekty.ncn.gov.pl/opisy/516283-en.pdf)
