|
摘要
基于Fluent软件平台,根据L+U形槽的三维结构特征及内部流场特征,提出一种L+U形槽过流面积的计算方法,推导了L+U形槽过流面积的计算公式,绘制出理论计算及流场仿真计算的L+U形槽过流面积曲线并进行了比较。
Based on Fluent software platform,according to the three-dimensional structure characteristics and internal flow characteristics of L + U slot,a calculation method for L + U groove flow area was proposed.The calculation formula of L + U groove flow area was deduced.The curves of the flow area calculated by theory calculation and flow simulation were drawn and compared.
