The Department of Transonic Flows is part of the Centre of Thermomechanics of Fluids, Institute of Fluid-Flow Machinery, Polish Academy of Sciences, Gdańsk, Poland.

Activities:

1. Experimental investigation of flow in boundary layer
   
   
   • natural and induced transition in boundary layer,
   • unsteady phenomena in boundary layer,
   • thermal boundary on a flat plate,
   • heat transfer in heated boundary layer,
   • modeling of boundary layer transition induced by wakes.
     
     
2. Experimental techniques for flow measurements
   
   
   • thermoanemometry,
   • simultaneous measurements of temperature and velocity fluctuations,
   • heat transfer measurements,
   • pressure and velocity measurements.
     
     
3. Wake generation and its investigation
   
   
   • wake interaction in turbomachinery,
   • interception of wakes, clocking effect and its modeling,
   • squirrel cage generator,
   • single cylinder in motion.
     
     
4. Engineering applications
   
   
   • axial fan design, development and investigation,
   • probes calibration for industry.
