Abstract
The engineering process of the IFMIF high flux test module (HFTM) demands concurrent optimization with respect to neutronic, mechanical and thermal-hydraulic issues. The cooling technology of the HFTM makes use of helium gas flowing in mini-channels along the specimen capsules. The coolant gas flows in these mini-channels are characterized by transitional Reynolds numbers, high velocities and high heating rates. Further, the flow in the short channels is influenced by entrance effects on a relevant part of the full length. The present study addresses these issues by experimental and numerical simulations. To this end, the experimental facility ITHEX has been constructed, and several mini-channel test sections were investigated using a variety of experimental techniques. The numerical methods are validated against the experimental data, and general conclusions on the HFTM thermal-hydraulic layout are presented.
