基于MATLAB软件编写了绘制支板流场流线和计算不同流线上气体流动时间的程序,并使用自编程序分析了一种无后掠支板的流场.计算结果表明,自编程序计算的流线和气体流动时间具有很高的可靠性;支板回流区中气体流动时间最长的位置位于支板中心线附近,流线漩涡中心处,该处气体流动速度最小.本方法为分析支板流场提出了一种新思路,能够最直接地反映支板营造回流区能力,为进一步设计新的支板结构奠定了基础.
Based on the MATLAB software, a program of drawing the streamline of the flow field and calculating the flow time of the gas on the different flowlines was compiled and a flow field of the non-swept support was analyzed by using the self-programmed program. The calculation results show that the self- Of the flow line and the gas flow time with high reliability; support the backflow zone gas flow time longest position near the centerline of the support plate, streamline vortex center, where the gas flow velocity is minimal.This method is to analyze A new idea is put forward for the flow field of the support plate, which can most directly reflect the ability of the support plate to create a recirculation zone, which lays the foundation for further design of a new support structure.
