以诗情画意之美,增益力学之美;以力学之美,欣赏诗情画意之美
我国是一个诗词的国度,有灿烂的诗歌文化,唐宋诗词更是我国文学史上一颗璀璨的明珠。古代诗词中有大量对力学现象的精美描写,体现了诗人对力学现象入细入微的观察与力学理性的思考。
通过欣赏古代诗词中对力学现象精湛描述的名篇佳句,将诗情画意与近代力学的发展交融在一起,将科学与艺术融于一体,使欣赏性、知识性、趣味性、科学性巧妙结合,以情、景、声、乐、视、画、图、文并茂的形式,生动鲜明的讲述方式,深入浅出、引人入胜地把力学原理和内在规律介绍给最广大范围的读者。
通过运用力学原理深入浅出地讲解身边的力学现象和力学问题,一方面传播力学知识,同时从诗歌中欣赏力学之美,体验力学趣味,感受力学魅力。以诗情画意之美,增益力学之美;以力学之美,欣赏诗情画意之美。
姜楠教授主讲“诗情画意谈力学”,欢迎大家鉴赏。

涡是流体力学中的重要现象,但迄今为止,人们对涡的认识还很模糊,还未能给出一个有物理意义和被广泛接受的定义方法。多年来人们尝试了多种方法,早期曾采用涡量方法,但后来发现涡量和涡结构的关联性不高。后来,又发展了多种以速度梯度张量特征值为代表的涡识别方法,如常用的Q,和等。但这些方法在实际使用过程中,研究者需要不停地调整阈值以获得一个主观确定的等值面效果。从2014年开始,美国德州大学阿灵顿分校的刘超群教授团队提出了涡识别方法和Liutex向量方法。涡识别方法定义为速度梯度张量反对称部分比上对称和反对称部分之和,当比值大于0.5可以认为旋转占优,其应用建议在0.52~0.6之间取值,可使得识别的涡结构基本保持不变。Liutex向量的核心思想是将涡量进一步分解为旋转部分(R)和非旋转部分(S),其中新分解出来的R部分代表流体运动的刚体旋转部分,其认为该空间矢量可用于表征旋涡结构。Liutex 给涡的研究提供了新的视角。

Call For Papers:International Symposium on High-Fidelity Computational Methods & Applications

Dec 14th ~16th, 2019 

Shanghai, China

Introduction & Objective

The original intention of organizing this symposium is to discuss recent advances of the high-fidelity methods and enhance deployment and industrial applications of the methods in complex fluid flows and related topics, which is enlightened by the 4th Nektar++ workshop 2019.

High-fidelity computational methods are emerging tools that underpin science and engineering. Due to the increasingly stringent precision requirements for industrial designs,  these methods have recently attracted even greater attention. This symposium will bring together world leading experts to discuss novel developments, new perspectives and industrial applications. The ultimate goal of the symposium is to expand the range of application of high-fidelity numerical tools in engineering practice.

During the symposium, a Nektar++ tutorial session will be run for the people who are interested in theories of spectral/hp element methods and parallel implementation of the methods. By the tutorial session, people will learn how to use Nektar++ to carry out high-fidelity high-efficient calculations and analyses for incompressible and compressible complex flows and how to write their own customized solvers by virtue of the Nektar++ hierarchical libraries.

Abstracts are invited on the research, application and deployment of high-fidelity methods with a particular interest in computational mathematics, aerodynamics and hydrodynamics.
