摘要
This paper uses a compressible homogeneous‑mixture Navier–Stokes solver with a high‑order interface‑capturing method to simulate single cavitation bubble collapse near rigid surfaces and analyzes spatial–temporal wall shear stress, boundary‑layer flow, and thermal effects; key results include identification of inward/outward shear regions and moving stagnation ring vortices, thermal boundary‑layer growth from skin friction, non‑dimensional correlations of maximum shear stress vs. normalized film thickness and impact pressure, and Prandtl‑number based correlations for primary/secondary peak shear stresses on heated surfaces [page::0][page::5][page::10][page::14]
