GSH Modification as a Marker for Plasma Source and Biological Response Comparison to Plasma Treatment

Applied Sciences, 10(6), 2025.

By: P. Ranieri n, H. Mohamed*, B. Myers n, L. Dobossy*, K. Beyries*, D. Trosan n, F. Krebs*, V. Miller*, K. Stapelmann n

Simulation scaling studies of reactor core two-phase flow using direct numerical simulation

Cambareri, J. J., Fang, J., & Bolotnov, I. A. (2020, March). NUCLEAR ENGINEERING AND DESIGN, Vol. 358.

author keywords: DNS; Interface tracking; PWR subchannel; Scaling studies
TL;DR: The state-of-the-art analysis of turbulent two-phase flows in complex LWR subchannel geometries are demonstrated at both prototypical reactor parameters as well as scaled low pressure conditions, leading to the generation of useful guiding principles when researchers need to scale the two- phase flow behavior captured at low pressure and temperature conditions to those at reactor operating conditions.
