摘要

复杂的流体存在于自然界中，并不断被设计用于特定的应用，包括在溶剂中添加大分子，以及其他方法。这赋予了流体粘弹性，这是导致各种流动不稳定性和流体动力学重大变化的特性。本文综述了用连续级微分本构方程描述黏弹性流体流动的数值模拟方法的最新发展，特别强调了有限体积方法。简要介绍了该方法，并介绍了目前计算流变学中用于评估数值方法性能的主要基准流程。讨论了数值方法中的突出问题和粘弹性流体的新颖和具有挑战性的应用，其中一些需要在数值方法中进一步发展。

Numerical Methods for Viscoelastic Fluid Flows

Complex fluids exist in nature and are continually engineered for specific applications involving the addition of macromolecules to a solvent, among other means. This imparts viscoelasticity to the fluid, a property responsible for various flow instabilities and major modifications to the fluid dynamics. Recent developments in the numerical methods for the simulation of viscoelastic fluid flows, described by continuum-level differential constitutive equations, are surveyed, with a particular emphasis on the finite-volume method. This method is briefly described, and the main benchmark flows currently used in computational rheology to assess the performance of numerical methods are presented. Outstanding issues in numerical methods and novel and challenging applications of viscoelastic fluids, some of which require further developments in numerical methods, are discussed.

期刊介绍： The Annual Review of Fluid Mechanics is a longstanding publication dating back to 1969 that explores noteworthy advancements in the field of fluid mechanics. Its comprehensive coverage includes various topics such as the historical and foundational aspects of fluid mechanics, non-newtonian fluids and rheology, both incompressible and compressible fluids, plasma flow, flow stability, multi-phase flows, heat and species transport, fluid flow control, combustion, turbulence, shock waves, and explosions. Recently, an important development has occurred for this journal. It has transitioned from a gated access model to an open access platform through Annual Reviews' innovative Subscribe to Open program. Consequently, all articles published in the current volume are now freely accessible to the public under a Creative Commons Attribution (CC BY) license. This new approach not only ensures broader dissemination of research in fluid mechanics but also fosters a more inclusive and collaborative scientific community.
