CLaBME

Central Laboratory of Power Generation Machines     ”CLaBME”

“CLaBME” as a specialist laboratory is designed for testing turbomachinery.

Its unique character results form the fact that includes the only anechoic chamber for aeroacoustic investigations in Poland, outputs of air flow, volumes of water tanks, electrical power available and measurement and control equipment that can be applied in scientific experimental investigations and R&D activities.

 

“CLaBME” comprises test stands, apparatus, installations, equipment and the staff of:

  •  Laboratory of  Fluid Mechanics

  •  Laboratory of Turbines and Compressors

  •  Laboratory of Hydromachines

  •  Laboratory of Automatics and Diagnostics

  •  Laboratory of Flow Metrology

  •  Laboratory of Medical Apparatus

  •  Mechanical Workshop

 

Central Laboratory of Power Generation Machines ”CLaBME” is equipped with:

Ø      LaVision FlowMaster system which evaluates three-dimensional velocity vector fields from scattered light patterns of particles or droplets seeded into the flow (liquid or gas). LaVision's FlowMaster camera systems can record two successive images within min. time <100 ns for ultrafast cross-correlation and speeds up to Mach 4. The PIV (Particle Image Velocimetry) cameras offer highest sensitivity and allow the use of very small particles (or droplets). Applications: liquid and gas flow investigations in wind tunnels, water channels, in-cylinder engines industrial flow systems, compressors, turbines, fans, pumps, Micro Electro Mechanical Systems (MEMS). Main data: frequency of laser pulse generation up to 10 KHz; pulse frequency – up to 2 x 200mJ; frequency of camera transfer up to 3kHz.

Ø      unique anechoic chamber (7.5 x 13.5 x 5.5 m) for aeroacoustic investigations of turbomachines at a free air flow – the only one in Poland and unique in Europe,

Ø      electric supply system -  power 2.5 MW and voltage 6 kV  - to drive compressors and pumps; the system comprises a gear transformer 15/6/0.4 kV, electric engines (power from 0.8 to 2.0 MW), accumulators, starters, distribution and control boards,

Ø      compressed air supply system: a three-stage CLARK compressor (flow 5.8 kg/s at the pressure ratio 9 or 8 kg/s at the pressure ratio 2.8)  and a one-stage compressor (pressure ratio 3, flow 14.4 kg/s) equipped with an acoustically damped system of air inlets and outlets,

Ø      water system for oil cooling installation for compressors and a closed water supply system for pumps, including: a drilled pump, 28 and 50 m3 water tanks, and a vertical water tank, 14-meter deep, to test drilled pumps,

Ø      fuel system for turboengine test stands with an exhaust take-off system, automatic control board and measurement cabin,

Ø      pressure tanks, installations, lifting jacks and a mechanical & electric workshop to maintain machines, installations and test stands,

Ø      wind tunnels for blade profile investigations and probe calibration for steady and unsteady flow measurements up to Mach number 0.8 and a test stand to calibrate pressure transducers,

Ø      test stands for investigations of non-conventional gas and magnetic bearing systems, including test stands for active control of rotating shaft vibrations,

Ø      system for automatic measurements of velocity, pressure and temperature in steady and unsteady flows, apparatus for contacless measurement of mechanical  displacements and determination of unsteady motion trajectory of shafts, apparatus for measurement and analysis of mechanical vibrations  with codes for modal analysis,

Ø      system for collection and computer analysis of the measurement results of parameters of the flowing liquid and the atomized jet,

Ø      licensed ANSYS CFX 11.0 software  plus auxiliary packages.
