摘要
根据几何关系,建立轴流通风机叶片平面样板及圆柱型样板的三维数学模型,据此用MATLAB编写参数化软件,计算风机叶片三维坐标值,绘制各截面曲线,并结合GAMBIT调用软件生成的叶片三维坐标数据文件,实现轴流通风机快速建模。利用此软件完成一个轴流通风机的造型实例,结果表明这种方法缩短了CFD前处理时间。
According to geometry relationship, the 3-D mathematical model of blade's plane and column template is established. MATLAB is applied to compile parameterized software, compute 3-D coordinate data of fan blade and draw sectional curves. Furthermore, the rapid modeling of axial-flow fan is realized based on the combination of blade's 3-D coordinate data producing by GAMBIT software. The result shows that this method can reduce the preprocessor time of CFD.
