【摘要】 利用数值模拟方法对波纹管内流场分别进行二维和三维数值模拟结果的比较研究,分析其可行性和存在的问题.研究结果表明,波纹管内流场的模拟可以将三维模型简化为二维模型对流场进行定性分析;通过改变波纹管的结构尺寸,说明轴对称元件的直径越大,结构越简单,二维和三维的模拟结果越接近.更多还原

【Abstract】 The comparison between the two and three dimensional simulation of corrugated tube was investigated,using computational fluid dynamics software package(Fluent).It was shown that the three-dimensional model can simplify into the two-dimensional model to analysis flow field qualitatively.The size of corrugated tube was altered,which was shown that the result of two dimensional simulation agrees with that of the three,when the diameter of axial symmetry element is greater and the structure is simpler.更多还原
