会议介绍

    会议主题(Theme)

    本次会议的主题是“粘弹性流动中的理论及机理”,重点关注粘弹性流体的非线性动力学。粘弹性流体在自然界和工程过程中广泛存在,并具有很高的实用价值。粘弹性流体动力学的科学研究具有丰富的历史,涵盖了广泛的研究课题,对理论、数值和实验研究人员都提出了重大的挑战。最近,该领域涌现出许多新的发现和讨论,包括新的粘弹性流体不稳定性现象和粘弹性流体公式的数学性质,因此本次研讨会是一个相关研究人员共同分享意见和展望未来方向的好机会。本次研讨会旨在强调与粘弹性流体相关的数学研究及其物理机理。具体而言,我们将涵盖以下主题:利用动力系统方法来理解粘弹性流体的动力学机制,粘弹性方程的解的存在性和光滑性,以及在粘弹性流体实验中观察到的非线性弹性波及其数学建模。<br/>

    The conference will explore the theme of "Theory and Mechanisms in Viscoelastic Flows," with a specific focus on the nonlinear dynamics of viscoelastic fluids. These fluids are ubiquitous in both natural phenomena and engineering processes and hold significant practical value. Understanding the dynamics of viscoelastic fluids has a rich history and encompasses a diverse array of research topics, presenting a significant challenge for theoretical, numerical, and experimental researchers. Recently, the field has witnessed a surge in new discoveries and discussions, including novel viscoelastic flow instabilities and mathematical properties of the viscoelastic equations, highlighting the need for researchers to come together to exchange ideas and explore future directions. The goal of this workshop is to emphasize the importance of mathematical research and physical mechanisms in viscoelastic flows. Specifically, the workshop will cover various topics, such as the application of dynamical systems approaches to comprehend the flow dynamics of viscoelastic fluids, the existence and smoothness of solutions to the viscoelastic equations, and the observation of nonlinear elastic waves in viscoelastic experiments and how they can be modeled mathematically.
