CFD Analysis of POT TESTER Impeller to Improve the Performance of Ash Handling Systems

Impeller deformation is a major problem that constantly affects the operation of the system for hydraulic transportation of solid waste material (such as ash). The design of the impeller with different-different type of material to improve the performance, optimization of slurry flow or strength of the impeller hydraulic transportation pump is analyzed by using Computational fluid dynamics package (ANSYS). CFD are carried out for analyzing of flow effects. The pot tester is designed for study of impact of pressure variation on impeller of slurry/hydraulic transportation system with high concentration. A 3D model generated using commercial software CREO and model is simulated for flow visualization using computational fluid dynamics, which results are closer to experimental result. The pot tester is designed on the accordance of our experimental setup specifications. This paper is based on analyzing the pressure variation impact of slurry on impeller. Computational investigation were conducted on the impeller with the velocity 1.5 m/s to 4 m/s. High kinetic energy is available at the surface of specimen due to high velocity which may causes wear or deformation on blade take place. In this paper, analysis taken the four material (brass, copper, titanium, stainless steel400) to get a suitable material for hydraulic transportation system and also increases the life of the systems.
