Flow Field Analysis And Structural Optimization Of Centrifugal Throwing Head

Research and development throwing snow type snow sweeper in the country is still in its infancy, domestic production of throwing snow type snow sweeper appeared big power consumption, low snow removal efficiency and poor ability to avoid obstacles. About the throwing snow type snow sweeper snow removal device research for the solution of the existing problems play a crucial role, so based on the CFD software of snow threw snow type snow sweeper head structure parameters of numerical simulation for domestic throwing snow type snow sweeper research and development has important significance. so numerical simulation of throwing snow head structure parameters for domestic throwing snow type snow vehicle research and development is important.In this paper, based on the CFD software numerical simulation ability to numerical simulation analysis and optimization of the throw the snow head structural parameters. By the internal pressure field and velocity field analysis of the throwing snow flow structure’s head, concluded that throw snow head internal gas-solid two-phase flow pressure distribution and velocity vector distribution parameter of the research and analysis results, and according to the structural parameters of the simulation data analysis put forward the corresponding optimization solution.In order to achieve numerical simulation and analysis of the flow inside the head throwing snow flow field, first of all, discusses the internal flow field of fluid medium, mainly to the physical and mechanical properties of snow was summarized and analyzed. In addition to calculation and analysis of performance requirements of control equation of the snow head structure. For the realization of the flow inside the head throwing snow modal analysis of gas-solid two phase flow, it also establish a three-dimensional model of the head throwing snow in the CFD software. By using Fluent software to throw the snow head for a numerical simulation in port. Through simulation analysis of snow threw the snow head mainly from the head of centrifugal fan and throw snow tube structure parameters are optimized, thus obtained the snow head to optimize the best way to improve. On the premise of guarantee the normal work of the snow sweeper, improve the efficiency of snow threw, reduce the power consumption of the throwing snow head, and the snow in the snow tube thrown behind can has the shape of the specification. Provide scientific arguments for throwing snow head of the throwing snow type snow sweeper structure design and production.
