Abstract

Fluid-conveying nanotubes have become important components of nanoelectromechanical systems (NEMS) working in fluid environments, exciting extensive research on the dynamics of flow-conveying nanotubes. This paper systematically reviews the research progress of mechanics of fluid-conveying nanotubes from several aspects, including tube displacement field, non-classical continuum theory models, modeling, governing equations, boundary condition treatments, and dynamic behaviors. First, a refined displacement field for the tube structure considering curvature nonlinearity is presented. Based on the generalized continuum theory, a size-dependent constitutive model of nanotubes is established that fully considers surface effects, non-local stress and strain gradient effects, as well as the slip flow model for modeling the size-dependency of nanofluid is derived. Subsequently, three types of planar nonlinear vibration problems related to boundary conditions of flow-conveying nanotubes are reviewed. Based on the different nonlinear characteristics caused by different boundary conditions, including curvature nonlinearity, inertia nonlinearity, boundary tension hardening nonlinearity, etc., corresponding assumptions are made and size-dependent longitudinal internal force-displacement relationship is established. The dynamic governing equations and classical and non-classical boundary conditions of flow-conveying nanotubes are derived based on the Hamiltonian variational principle. The current main treatment methods for non-classical boundary conditions are illustrated. Finally, the research status of mechanical behaviors of fluid-conveying nanotubes is reviewed and future research prospects are summarized. This article provides theoretical guidance for linear/nonlinear design of NEMS of next-generation working in fluid environments.

纳米管流体输送力学综述
流体输送纳米管已成为在流体环境中工作的纳米机电系统(NEMS)的重要组成部分,激发了人们对流体输送纳米管动力学的广泛研究。本文从纳米管位移场、非经典连续理论模型、建模、控制方程、边界条件处理和动力学行为等几个方面系统回顾了流体输送纳米管力学的研究进展。首先,提出了考虑曲率非线性的管结构精细位移场。在广义连续性理论的基础上,建立了充分考虑表面效应、非局部应力和应变梯度效应的纳米管尺寸依赖性构成模型,并推导出纳米流体尺寸依赖性的滑移流模型。随后,综述了与纳米管流动输送边界条件相关的三种平面非线性振动问题。根据不同边界条件引起的不同非线性特性,包括曲率非线性、惯性非线性、边界拉伸硬化非线性等,提出了相应的假设,并建立了与尺寸相关的纵向内力-位移关系。根据哈密顿变分原理,推导出流动输送纳米管的动态控制方程以及经典和非经典边界条件。说明了当前非经典边界条件的主要处理方法。最后,回顾了流送纳米管力学行为的研究现状,并总结了未来的研究前景。本文为在流体环境中工作的下一代 NEMS 的线性/非线性设计提供了理论指导。

期刊介绍: The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
