Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Temporal instability of liquid-metal flow in a square duct is investigated using a two-dimensional Chebyshev collocation method. In this study, the flow is subjected to a transverse magnetic field. The wall of the duct perpendicular to the magnetic field and the left parallel wall is perfectly conducting whereas the right parallel wall is insulating. Neutral stability curves are obtained for different Hartmann numbers. The five influencing factors of the instability are analyzed by energy analysis of perturbations. With the increase of Hartmann number, the critical Reynolds number first decreases rapidly and then increases gradually. The turning point of the variation of Rec with Ha is at Ha ≈ 20.4. When Ha < 20.4, velocity shear near the inflection point plays a dominant role in leading to the flow instability. When Ha becomes >20.4, perturbations produced by the inflectional velocity profile and Tollmien-Schlichting waves in the side layer are elongated by the nonuniform velocity in transverse direction; thus, the flow instability is caused by the combined effect at a much lower Reynolds number.
