Abstract

Abstract

En 中文
• Developed physics-driven method for multi-body non-matching interfaces, ensuring conservation without mesh edits. • Robust algorithm works with structured/unstructured meshes via dual-weighting for efficiency and versatility. • Validated in complex reactor pressure vessel simulations with intricate multi-body geometries: 0.586% pressure error and 1.645% flow error vs. continuous meshes. • Enables tight-coupled FSI conjugate heat transfer for multi-body systems, preserving coupling accuracy across non-matching interfaces while capturing fluid-solid thermal interactions.
