The objective of the proposed post-doc program within the LBE research team is to develop and apply a methodology for the experimental investigation of:
- the overall heat transfer coefficient of double-walled PHX tubes
- the mechanical behavior of these double-walled PHX tubes under high thermal loads from temperature gradients
For this purpose, one or more scaled test set-ups have to be developed, respecting the thermal-hydraulic and mechanical behavior in a limited-size tube bundle that is to be implemented in the COMPLOT facility.
Moreover, suitable experimental techniques have to be selected and implemented taking into account the limitations presented by the harsh LBE environment and the strong temperature gradients expected.
Finally, the experimental campaign should be performed and the experimental data should be analyzed to formulate correlations for heat transfer coefficients and guidelines for mechanical design that can be used by the design team.
The post-doc will receive support from the COMPLOT design engineer for the design and integration of the test section(s) in the existing experimental facility at SCK•CEN. The necessary provisions for coupling the test section(s) to a steam/water secondary loop are under preparation. The complete facility will be operational early 2018.
