摘要

基于早期发展的两个垂直方向上的双旋转复杂流动的数学模型，本文进行了稳定性分析。Navier-Stokes方程是在围绕两个垂直的不同轴旋转的坐标系中导出的，其中一个垂直轴与另一个旋转轴相距一定距离，水平轴沿垂直旋转圆的切线定向。两个离心力和科里奥利力在高振荡流中产生了独特的特征，由于它们的作用因通道流中的周向圆柱坐标而变化，拉伸液体的位置也随之变化。首先考虑了在产生强烈变化的质量力和液体拉伸的双重旋转下的复杂旋转流的稳定性分析

Stability Analysis for Complex Rotational Flow

Based on the earlier developed mathematical model of the complex flow due to the double rotations in two perpendicular directions, the stability analysis is performed in the paper. The Navier-Stokes equations are derived in the coordinate system rotating around the two perpendicular different axes, the vertical one of them is arranged on some distance from the other axis of rotation, the horizontal axis is directed along the tangential line to the circle of the vertical rotation. The two centrifugal and Coriolis forces create the unique features in high oscillating flow, with localities of the stretched liquid, due to their action varying by the circumferential cylindrical coordinate in the channel flow. Stability analysis for the complex rotational flow under double rotations creating strongly varying mass forces and stretching of the liquid is considered at first

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
