In this paper the internal flow patterns of a sludge pump with three different recessed centrifugal impellers were analyzed based on CFD by using the turbulence model to close the time-averaged Navier-Stokes equations.
In this paper the three-dimensional internal flow fields of sludge pumps with recessed centrifugal impeller, a kind of no-clogging pump, were numerically simulated by means of computational fluid dynamics and famous commercial CFD software Fluent.
Since the model test of sludge with real mud or sludge will be very difficult and expensive, so that the fluid to be used in simulation is clean water at 200C in initial design stage.

Computational Fluid Dynamics (CFD) is one of the methods that can be used to study the nature of turbulent flow especially in the aspect of wind engineering besides the experiment at full scale of reduced scale (wind tunnel experiment).
Large Eddy Simulation (LES) is a promising way for the simulation of wind flow fields and pollutant dispersion [6], though it is still restricted by the capability of today’s computers.
The simulation was run for 30 min of simulation time without pollutant source in order to establish the turbulent wind fields throughout the domain and all statistics are averaged at least for 15 min.
These factors contribute to the quality of the resultant simulation.
