| Abstract: | Based on the expressions for the force applied on the particle in a flow field, the general solution for the trajectory of the moving particle in stationary and rotational coordinate sys- tems in the case of low Re has been derived, and the equation of the trajectory has also been obtained in the case of high Re. A method for calculating the runner potential flow is given and, as an example, the meridional flow field of GH200-W-35 is also given. The trajectories for particles with different diameters in the runner of the Francis turbine are calculated. Results of calculation are very close to those obtained by K. Minemura. |
