Special-shaped section pipeline design method and system based on additive manufacturing and terminal

According to the special-shaped section pipeline design method and system based on additive manufacturing and the terminal, the special-shaped section pipeline is designed by combining the initial design parameters of the circular section multi-channel structure, and it can be guaranteed that when the pipeline streamline is in the horizontal direction, printing can be directly conducted without adding an internal support; and the geometric parameters of the special-shaped section have little influence on the flow characteristics of fluid in the micro-channel, and the method has engineering application value. Compared with a multi-channel structure obtained through a traditional preparation technology, the weight of the multi-channel structure can be reduced, meanwhile, the size of the multi-channel structure is reduced, and integrated design is achieved. 本发明的基于增材制造的异形截面管道设计方法、系统以及终端，通过结合圆形截面多通道结构的初始设计参数设计出异形截面管道，可保证管道流线为水平方向时不需要添加内部支撑即可直接打印，且异形截面的几何参数对微通道内流体流动特性的影响不大，具有工程应用价值。与相比较采用传统制备技术得到的多通道结构相比，本发明可减轻多通道结
