Abstract: Numerical simulation of three-dimensional flow in whole flow passage of axial flow
hydraulic turbine was conducted based on the Reynolds-averaged N-S equations and the
standard k-Ε model. Stress analysis of axial flow blade were carried on by elasticity unsteady FEM.
The fluid domain and solid domain were calculated by sequential iteration. Based on weak
coupling technology, the fluid-structure interaction analysis of the axial flow blade was conducted.
Instantaneous flow field characteristic and stress distribution on blade were analyzed. According
to the comparing with the results of pure flow numerical simulation, the pressure difference
between press side and suction side increases after considering the FSI, to a certain extent, which
