On the Particle Motion in a Flow field in Hydraulic Turbomachines

Liu Xiaobing;Cheng Liangjun  
An analysis is made of the forces acting on the solid particles in an arbitrary flow field.The Suffman force due to the velocity gradient and Magus force due to the particle rotationneglected in many earlier papers are considered in this paper. The equation for particle mo-tion in a flow field in hydraulic turbomachines is derived with Nowton's Second Law,A nu-merical method for solving the 3-D particle motion equation is given and the calculation re-sults for that in a Francis turbine runner have been obtained.
