Transporting of nanomachines using the nanoplates has been acknowledged as an emerging frontier of nanotechnology over recent years. This paper investigates the aerodynamic response of a temperature-dependent functionally-graded composite nanoplate reinforced by wavy carbon nanotubes (FG-WCNTRC nanoplate) under a nanoparticle moving in a straight path exposed by air drag. The meshfree finite volume (MFV) approach is implemented to develop the governing equations based on the Mindlin's plate and Eringen's non-local theories. Therefore, one uniform distribution and three linear distributions of wavy CNTs are considered through the thickness of the FG composite nanoplate. Moreover, a generalized rule of mixtures is employed to predict the mechanical properties of the nanoplate. In this sense, the material properties of the matrix and wavy CNTs are presumed to depend on temperature. A comprehensive investigation is then carried out for the first time to assess the effects of nanoplate elastic foundation coefficients, nanoparticle velocity, temperature dependency of material, volume fraction, waviness, distribution pattern, and orientation of the wavy CNTs on the amount of air drag effect. It is revealed that in the aerodynamic response of temperature-dependent FG-WCNTRC nanoplates under a moving nanoparticle, the air drag amount can be influenced considerably by the material properties of the nanoplate.

使用无网格有限体积法对移动纳米粒子下的温度相关 FG-WCNTRC 纳米板进行空气动力学分析

近年来,使用纳米板运输纳米机器已被公认为纳米技术的新兴前沿。本文研究了由波浪形碳纳米管(FG-WCNTRC 纳米板)增强的温度相关功能梯度复合纳米板在纳米颗粒在空气阻力暴露的直线路径中移动时的空气动力学响应。实施无网格有限体积 (MFV) 方法以开发基于 Mindlin 板和 Eringen 非局部理论的控制方程。因此,通过FG复合纳米板的厚度考虑波状CNT的一种均匀分布和三种线性分布。此外,采用混合物的一般规则来预测纳米板的机械性能。在这个意义上,假定基体和波浪形碳纳米管的材料特性取决于温度。然后首次进行了全面调查,以评估纳米板弹性基础系数、纳米粒子速度、材料的温度依赖性、体积分数、波纹度、分布模式和波浪状碳纳米管的取向对空气阻力效应量的影响. 结果表明,在移动纳米颗粒下的温度相关 FG-WCNTRC 纳米板的空气动力学响应中,空气阻力量会受到纳米板材料特性的显着影响。波浪形碳纳米管的体积分数、波纹度、分布模式和方向对空气阻力效应的影响。结果表明,在移动纳米颗粒下的温度相关 FG-WCNTRC 纳米板的空气动力学响应中,空气阻力量会受到纳米板材料特性的显着影响。波浪形碳纳米管的体积分数、波纹度、分布模式和方向对空气阻力效应的影响。结果表明,在移动纳米颗粒下的温度相关 FG-WCNTRC 纳米板的空气动力学响应中,空气阻力量会受到纳米板材料特性的显着影响。
