Fluid mechanics has emerged as a basic concept for nearly every field of technology. Despite there being a well-developed mathematical theory and available commercial software codes, the computation of solutions of the governing equations of motion is still challenging, especially due to the nonlinearity involved, and there are still open questions regarding the underlying physics of fluid flow, especially with respect to the continuum hypothesis and thermodynamic local equilibrium. The aim of this Special Issue is to reference recent advances in the field of fluid mechanics both in terms of developing sophisticated mathematical methods for finding solutions of the equations of motion, on the one hand, and on novel approaches to the physical modelling beyond the continuum hypothesis and thermodynamic local equilibrium, on the other.

物理和数学流体力学

流体力学已成为几乎所有技术领域的基本概念。尽管有完善的数学理论和可用的商业软件代码，但控制运动方程的解的计算仍然具有挑战性，特别是由于涉及非线性，并且关于流体流动的基础物理学仍然存在悬而未决的问题，特别是关于连续统假设和热力学局部平衡。本特刊的目的是参考流体力学领域的最新进展，一方面是开发用于寻找运动方程解的复杂数学方法，另一方面是超越连续体的物理建模的新方法另一方面，假设和热力学局部平衡。
