Tallinn University of Technology

Laboratory of Fluid Mechanics

The main research fields of TalTech’s Laboratory of Fluid Mechanics are associated with hydro mechanical processes in natural and artificial hydraulic systems.

Laboratories’ tasks include experimental and other lab services, development of new experimental methods and providing knowledge needed in research, development and learning activities. In recent years the lab has been renovated and equipment used in experimental studies has been upgraded and modernized to improve the overall quality of services.


TalTech’s Laboratory of Fluid Mechanics can be found from the TalTech’s main complex, study building U03, room U03 106-108.

The heart of the Laboratory of Fluid Mechanics is located underneath its floor – a basin with a capacity around 150 m3, which supplies all the test rigs with water.

The 22 m long water channel, is one of a kind in the near region, allowing to experimentally study different hydro technical structures, costal processes, sediment movement etc. In addition the lab is equipped with a number of pipe test rigs.

The staff working in the Laboratory of Fluid Mechanics has participated in numerous international experimental research projects and has high competence in the field.

Laboratory tests:

  • The durability of pipes, mountings and fittings to internal pressure according to standards ISO1167, 4427, 4437.
  • Model tests of hydro technical structures (dams, embankments, overflows, culverts, etc).
  • Analysis of water quality and other parameters in natural and laboratory conditions. Labs’ equipment enables to measure in rivers, creeks, catchment areas etc locally 3D velocity components; in addition temperature, air content, conductivity, pH, salinity, if necessary, ammonium, nitrate, and chloride concentration in water.
  • Hydrodynamic processes in case of pipe emptying and filling.
  • Flow measurements in open channels (storm water, sewer systems etc)
  • Local rainfall measurements.
  • Visualization of flow structures.
  • One and two dimensional flows in wind channels, aerodynamic processes.
  • Determine particle size (0,01-3500 µm).
