Phase Flow Sedimentation Model And Numerical Simulation

The process of settling is a solid-liquid separation process. It is also a multi-level and multi-material mixing process, which involves fluid mechanics, applied mathematics, reactor engineering disciplines and so on. Settling behavior is a very complex phenomenon that is not easily described fully by people. Over time, the need of the process of settling application is increasing, it rises a activity of settling model research of home and abroad. This upsurge develops the settling theory, settling model and solid-liquid separation technology.Settling model is the key to the settling theory application. This paper first reviews the settling theory development nearly a century, and then combines with home and aboard research on the settling model, establishes the one-dimensional settling model by the computer, and generates simulation software to simulate the process of settlement. We can simulate the different results from the different materials by the software, and get a conclusion by analyzing the results. The software design bases on easy-to-use, simple, flexible, analyzes the function of the settling model, uses the finite difference method to solute the model, and finally finishes it. By the software, users can directly simulate it, there is no consumption of equipment, energy and material, even if there is a error, it will not cause losses, which greatly reduces the research costs; At the same time, given the rapid simulation results can be improve the process design in time and shorten the production cycle to prepare, responded to the market quickly. Finally, this article summarizes the research results, pointing out that the next step of the study contents.
