Theory of elliptical cylinder flow
摘要
Abstract
The distribution figures of the flow field surrounding the elliptical cylinder had been given in the current fluid mechanics theory. However, theory analysis and calculation process are not perfect, and it increases the difficulty for further study of elliptical cylinder flow. Firstly, based on the comformal transformation theory, zero angle attack of elliptical cylinder flow complex potential expression is obtained. According to the complex function theory, the complex potential expression is separated, and the potential function and the stream function are reached. Then, distribution figures of the flow field is drawn by MATLAB software. Based on potential function, the stream function and ideal fluid mechanics theory, the distribution of fluid pressure on the ellipsoid is di-scussed.关键词
