Abstract
The asymmetric part of flow over a body of revolution at high angle of attack is considered as coherent structures of the flow and a method of Proper Orthogonal Decomposition (POD) is applied to construct its low-dimensional model in the form of superposition of orthogonal functions. Results of the analysis show that the flow can be represented in the form of linear combination of odd and even functions, and the first two terms of the expansion capture 98.5% of its kinetic energy. Their coefficients are determined by the value of side force and the increment of normal force. The transient behavior of the flow is studied using Fourier transformation.
