摘要

基于非定常动量源方法结合计算流体力学(CFD)研究了轴向下降转子流场结构的演化特性。重点分析了涡环状态起始和退出时的速度临界值及其流场结构的变化特征。拉格朗日相干结构(LCS)分析结果揭示了管状滑流与环形涡之间切换的特殊性,表明了VRS演化过程中流场结构的临界变化特征。该方法确定的这些临界特征,即流动结构变化所描述的VRS边界,与已有的理论和实验结果一致,验证了所建立的分析方法研究该类边界的可行性。这项工作为研究VRS边界提供了一个强大的框架,并为进一步研究潜在的流动机制提供了见解。

Boundary criterion of vortex ring state for axially descending BO-105 rotor based on unsteady momentum source method

Boundary criterion of vortex ring state for axially descending BO-105 rotor based on unsteady momentum source method

This paper investigates the evolution properties of the flow field structure for axial descent rotor based on the unsteady momentum source method combined with the Computational Fluid Dynamics (CFD). The study focuses on analyzing the speed critical value during the onset of or exit from the Vortex Ring State (VRS), and its changing characteristics of the flow field structure. Results from the Lagrangian Coherent Structure (LCS) analysis reveal the switch particularity between the tubular slipstream and the annular vortex, suggesting the criticality change character on flow field structure which occurs in the evolution process of VRS. These criticality features, that is the VRS boundaries described by the flow structure change, as determined by this method, are consistent with the existing theoretical and experimental results, verifying the feasibility of the established analysis method in the study of such boundaries. This work provides a robust framework for studying VRS boundaries and offers insights for further research on the underlying flow mechanism.
