Critical Density Triplets for the Arrestment of a Sphere Falling in a Sharply Stratified Fluid a moderate Reynolds number of approximately 20–450 indicate that a sphere with the precise critical density, higher than the bottom layer density, can display behaviors such as bounce or arrestment after crossing the interface. We experimentally demonstrate that such a critical sphere density increEnrage 发表于 2025-3-29 01:35:34
Numerical Investigation of Incompressible Fluid Flow in Planar Branching Channelsation techniques. The methods are briefly described, pointing out the main differences in their behavior and numerical implementation on different types of grids. The newly developed finite difference immersed boundary code is compared with two in-house and open-source finite volume methods. The mut口诀 发表于 2025-3-29 06:58:04

Reduced Order Model Closures: A Brief Tutorialder-resolved simulations. Then, we construct step by step the ROM closure model by extending the classical Galerkin framework to the spaces of resolved and unresolved scales. Finally, we develop the data-driven variational multiscale ROM closure, and then we test it in fluid flow simulations..Our tuMirage 发表于 2025-3-29 16:22:12
Artificial Stress Diffusion in Numerical Simulations of Viscoelastic Fluid Flowshe classical Oldroyd-B model is considered as an example and prototype of viscoelastic rate type fluid models. The broader concept of numerical diffusion is presented, with special focus on tensorial artificial stress diffusion that proved to be a valuable tool in stabilizing the viscoelastic fluidbuoyant 发表于 2025-3-29 22:41:59

Circular Causality and Function in Self-Organized Systems with Solid-Fluid Interactionstual constraint emerges from the nonlinear interactivity between the constituents and the driving nonequilibrium boundary conditions. We review here interesting self-organized dynamics in systems where this interactivity among solid elements is mediated by an embedding fluid. In separate electricaloverbearing 发表于 2025-3-30 07:28:05
