Résumé

Flow and heat transfer performance of the cryogenic heat exchanger is always concerned. This paper studied flow and heat transfer performance of a special cryogenic heat exchanger, which is actually a neutron moderator cell (NMC) operating in a cold neutron source (CNS) of a reactor. A 3-D numerical modeling of heat transfer in NMC was built, and the modeling was verified by a simulating experiment. In the simulating experiment the liquid hydrogen boiling in NMC was replaced by Freon-R113, the cold helium of 17.6 K flowing in the sub-cooling passage was replaced by the cold nitrogen, and the heat generated by nuclear heating was simulated by an electrical heating. The numerical modeling was used to estimate heat transfer and pressure drop of NMC in CNS operating condition.
