| Abstract: | Based on the variational principle in ref. 4] and combined with the finite element method, a variational finite element method with variable domain for solving fully three-dimensional flow field in the rotor of turbine meter is suggested in this paper. The distribution of velocity in whole flow field is obtained. According to the solved flow field and the boundary layer theory,the distribution of viscous resistnace on blade and hub surface is proposed.The calculated characteristic curve is in good agreement with the experimental result. |
