CFD SIMULATION OF FLUID FLOW IN AN AGITATED SYSTEM WITH A PITCHED BLADE WORN IMPELLER
Original language description
This paper presents an analysis of the velocity field in an agitated fully baffled cylindrical vessel with a down pumping four blade worn or unworn pitched blade impeller (? = 45°) under a turbulent flow regime. CFD simulations were used to describe of the ensemble-average mean velocity field with worn and unworn impellers and their pumping capacity. It follows from the simulation results that the wear rate of the impeller blade has a significantly negative effect on the velocity distribution in an agitated liquid. The higher the destruction of the worn blade, the higher is the deformation of the velocity field around the rotating impeller with a simultaneous decrease in impeller pumping capacity.
