Simulation and Experiment of Water Thrust of Wastewater-Treatment Mixer

As the thrust of wastewater treatment mixer is a blank in current research in domestic, hydrodynamic analysis on the blade of the wastewater treatment mixer was used in this paper based on lifting theory of fluid mechanics, and the calculation formula of hydraulic thrust was deduced and demonstrated, which is significant in theory and valuable in practice. After analysis, the hydraulic thrust of wastewater treatment mixer is its axial force. A wastewater treatment mixer was simulated by using FLUENT6.2 software. The correctness of the theoretical analysis and feasibility of numerical simulation in wastewater treatment mixer application was confirmed by comparison, providing a certain directive function on engineering practice.
