Effect of Sand Particle Size on Sand–Water Flow in a Francis‐99 Distributor
ABSTRACT To examine the sand–water flow characteristics in the distributor of the Francis‐99 hydraulic turbine, numerical simulations were conducted using the Mixture multiphase flow model, focusing on the impact of varying sand particle sizes. The findings indicate that near‐wall velocities of sand and water in the fixed and guide vanes of the ...
