| Slurry Pump is widely used in water conservation. It is used to deliver the fluid of high density which is formed by solid-liquid mixed. The design of the slurry pump usually based on the work condition of delivering water,which lead to the low operational efficiency,high noise and heavy coneentrated wear;lead to largely waste of the energy and equipment , so it is very important to know about the flowing distributions.Experiment is the most direct and trusty but the investment is very large, the period is very long. The analyzing ability on the flowing fields and the remote flow structures will also be restrieted。But use the CFD software to simulate the Inner Flow Field cast lowly and it can reflect the distribution of the inner Flow Fieldcorrectly and direetly.The entity model of slurry pump is generated,used the more mature model to enclosed equation the equation.adopt the limited volume method to the enclose equations set,press amendment use the SIMPLE algorithm in this paper. Two different grain sizes and two different inlet initial solid phase consisteney have simulated in this paper by using FLUENT software.It can offer some reference information to the improvement of slurry pump's antiftaying nature and optimum design. |
