The MRI Flow Lab is designed to investigate complex flow systems and experimental setups with flow rates from a few liters per minute up to 1500 l/min. Experimental setups can be examined for several days or weeks to produce quantitative data that meet the stringent requirements for experimental data in engineering applications, such as the validation of CFD methods. The laboratory received funding as a DFG core facility in 2022. With this DFG core facility funding, it is possible for the team to share its unique measurement capabilities and experience for planning and conducting experiments with other research groups and to work collaboratively on future joint measurement campaigns and projects.


Multiphase flows

Besides single-phase flows, MRV enables measurements in multiphase flows. For example, in water-air-flow MRV provides the time-averaged velocity field and concentration of the liquid phase.


Porous media

Porous Media

Depending on the dimension of the porous media, MRV can either resolve the flow field inside the individual internal structures or it provides the mean velocity field of the liquid.


Periodic flows

Periodic Flows

MRV allows phase-averaged measurements in periodic flows at about 70 frames per second for a 2D measurement.


CFD validation

Automated matching and comparison routines of MRV and CFD results offer a fast and efficient full-field validation of numercial methods.





Measurement of millions of vectors of the mean velocity in a 2D or a 3D region of interest within a few hours.



Turbulence quantification by measuring the standard mean deviation of the velocity.



2D or 3D temperature measurements with 1 K accuracy in a range of 10 °C to 70 °C.



Quantification of stationary mixing processes in 2D or 3D.

New Funding Opportunity for Research Projects at the MRI Flow Lab

The MRI Flow Lab is now listed in the European User Facility Network Catalogue (OFFERR project)

The European User Facility Network Catalogue of the OFFERR project features over 180 specialized laboratories, including several Helmholtz facilities in Germany. Researchers and developers in the field of sustainable nuclear engineering can apply for exclusive OFFERR funding for research activities at these key facilities. The MRI Flow Lab has now been added to this catalogue, which underlines its value for Nuclear Reactor Safety studies as demonstrated in several research projects in the past years. This achievement allows European scientists to apply for OFFERR funding and use the infrastructure of the MRI Flow Lab for their research without further costs. Two options are available: fast-track for up to six months and 50k € or complex projects for up to 18 months and 1M €. The funding is open for proposals that address the strategic research and innovative agenda (SRIA) of the Sustainable Nuclear Energy Technology Platform (SNETP).

Best Paper Award for the article to Turbo Expo 2022

Each year the committees of The American Society of Mechanical Engineers Turbo Expo Technical Conference select a paper to receive their committee's best paper award. In 2022, our contribution which we worked on together with our colleagues from MAN Energy Solutions and Texas A&M University was chosen as one of the best papers by the heat transfer committee. The paper entitled "Assessment of the Flow Field and Heat Transfer in an NGV using Magnetic Resonance Velocimetry, Thermochromic Liquid Crystals and CFD" presents a combined experimental and numerical study on the flow field an heat transfer in a turbine blade cooling system.

Lecture on Magnetic Resonance Velocimetry in Fluid Mechanic Experiments

We are delighted to invite you to an upcoming lecture on Magnetic Resonance Velocimetry (MRV) in Rostock on June 14th 2023. Our speakers share insights and knowledge on the measurement principles of MRV and its applications in fluid mechanics & engineering, discussing the latest developments and research in the field. The lecture will be followed by live MRV experiments at the DFG core facility “MRI flow lab”, giving attendees the opportunity to engage with this unique measurement technique. This hybrid event (lecture and demonstration) is open to all who are interested in magnetic resonance techniques for fluid mechanics, and we would be honored to have you join us for this special occasion. We look forward to seeing you there!

Participation free of charge in person and online. Please register by June 7th at
