Weakly Compressible Approximation of the Taylor–Green Vortex Solution
Studies in Applied Mathematics, Volume 154, Issue 1, January 2025.ABSTRACT The Taylor–Green vortex represents an exact solution of the Navier–Stokes equations in R2$\mathbb {R}^2$. In this work, an approximation of this solution in two spatial dimensions is proposed for weakly compressible flows. These flows are characterized by small compressibility (or, equivalently, by a small Mach number) and are often employed ...

Study on Fuel Rod Melting and Molten Material Migration in Core Channels Based on Particle Method
Science and Technology of Nuclear Installations, Volume 2025, Issue 1, 2025.During nuclear reactor accidents where cooling fails, fuel rod melting and subsequent molten material flow through core channels critically determine disaster progression. Using advanced particle‐based simulation (MPS) with enhanced heat transfer, surface tension, and phase‐change modeling, this study reveals: Zirconium alloy cladding undergoes complex
