Thermal hydraulic experiments for nuclear technology, chemical and process engineering up to 7 MPa and 286°C

The thermal hydraulic test facility TOPFLOW (Transient TwO Phase FLOW test facility) is one of the major research facilities at Helmholtz-Zentrum Dresden – Rossendorf e.V. It was designed for generic and applied research of steady state and transient two-phase flows. TOPFLOW can be used to investigate thermal hydraulic phenomena in air/water- or steam/water flows in pipes and vessel geometries of industrial relevance. In the past years different projects for safety analysis in nuclear engineering and for chemical engineering as well as for the oil industry were performed. The test facility can supply media with the following parameters:

  • Saturated steam: pressure < 7 MPa, temperature < 286°C, mass flow < 1.4 kg/s,
  • Saturated water: pressure < 6.5 MPa, temperature < 281°C, mass flow < 50 kg/s,
  • Air: pressure < 0.7 MPa, volume flow (normal conditions) < 750 m³/h,

TOPFLOW is equipped with with special measurement techniques for flow structure and heat transfer studies (wire mesh sensors, needle shape probes, gamma ray tomography, X-ray tomography, high speed cameras, infrared cameras).

We offer:

  • Thermal hydraulic studies of two-phase flows in pipes up to 200 mm diameter,
  • Tests of hydraulic components and assemblies (Ø < 0.5 m, length < 3 m) using saturated steam and water up to 6.5 MPa,
  • Experiments with test rigs (Ø < 2 m, length < 5 m) at pressure up to 5 MPa and temperature inside the pressure chamber < 50°C,
  • Consultancy regarding design, technical engineering and assembling of test rigs,
  • Consultancy regarding measurement technologies and concepts
