ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

We propose a new RANS model for turbulent channel flows imposed wall-normal magnetic fields with heat transfer. This proposal model can be ensured adequate MHD effects on model functions and parameters in the turbulent eddy viscosity and the production minus destruction term of the epsilon-transport equation. With this new proposal model, the Nusselt number of several Prandtl number fluids (Pr = 0.025, 5.25 and 25) under the magnetic fields can be predicted in the range of less than 5% errors compared with the DNS database. The application possibility of this model is in the ranges of Ha2/Reτ2 less than 0.05.
