PhD in Experimental Clearance Flow Research

Technical University of Denmark; Kongens Lyngby; On-site; DKK 301,000 - 357,000; Full time

Job summary

The PhD candidate will join a collaboration between a private enterprise and DTU Construct to perform experimental clearance flow research with ammonia and sustainable marine fuels on an in-house test rig. The project will explore pressure and temperature regimes similar to a marine engine booster pump, using measured data to build and validate flow models.

Responsibilities include conducting test campaigns, developing both theoretical and experimental foundations for ammonia-compatible sealing

Qualifications

• Demonstrated ability to design and interpret high-pressure ammonia flow experiments.
• Experience with data processing of large experimental data sets.

Responsibilities

• Continue development of high-pressure ammonia flow rig.
• Conduct test campaigns with different ammonia pump components.
• Develop theoretical and experimental foundations for ammonia sealing techniques.
• Safe handling of ammonia and liquified gases in test setups.
• Design and wiring of electronic data acquisition and control systems.
• LabView programming for data acquisition.
• Mechanical design and FEM analysis using SolidWorks.
• Data processing of large data sets using Matlab.
• CMM measurement and Calypso software experience is advantageous.

Job description

The PhD candidate will, as part of a collaboration project between a private enterprise and DTU Construct, carry out experimental clearance flow research with ammonia and other sustainable marine fuels. Pressure and temperature conditions, resembling those in a marine engine booster pump, are created in an in-house designed clearance flow test rig. Measured clearance flow data will be used to develop and validate accurate flow models. The test rig will be further modified to enable testing and evaluation of different sealing solutions.

Responsibilities and qualifications

The PhD candidate will be responsible for continuing our development of a high-pressure ammonia flow rig, conduct test campaigns with different ammonia pump components and develop both theoretical and experimental foundation for developing ammonia compatible sealing techniques.

• Safe handling of ammonia and other liquified gases in test setups.
• Design and wiring electronic data acquisition and control systems using PC Schematics.
• LabView programming.
• Mechanical design and FEM analysis using Solid Works.
• Data processing of large experimental sets of dynamic flow and pressure data using statistical methods in Matlab.
• CMM (Coordinate Measurement Machine) measurement and preferably have experience with Calypso Software.
• Data processing large complex geometric data sets from CMM measurements for 3-dimensional analysis of tested pump components.
