摘要
在实际计算时，流体的求解域往往是有限的，这样就存在一个开口边界条件问题．Ｐａｐａｎａｓｔａｓｉｏｕ提出了自由边界条件或称无边界条件，很好地解决了开口边界问题．本文将在现有文献的基础上，进一步阐述了边界条件及其实质．
Owing to limitations in computing power and means, large domains are truncated, and artificial boundary conditions must be introduced. Papanastasiou and his colleagues have proposed effective free boundary conditions or no boundary conditions to solve the boundary condition dilemma. In the paper, the auther has further studied the open boundary conditions in a view of variational theory.
