概要

• 論文の詳細を見る

• Based on a unified Variable-domain variational theory (Liu, 1988), a new finite element method (FEM) with self-adjusting nodes for determimng the unknown boundaries (shape of the blade and of the annulus walls) in hybrid problems is presented. Two hybrid problem types H_A D and {H_C+D} D are tested numericaly by this FEM and the geometry of the rotor bladings thus obtained coincides with the original one quite well. Thus, a new numerical method with great generality and versatility for practical 3-D blading design and/or modification is provided.
