COMPUTER SIMULATION OF A HYDRODYNAMIC APPARATUS IN PULP AND PAPER PRODUCTION
The article presents a method for creating a mathematical model for solving an internal hydrodynamic problem in the SolidWorks application software package. The use of 3D modeling technology, computational fluid dynamics (CFD) and mathematical modeling of the efficiency of the device will allow us to consider many alternative design options and choose the optimal one among them, including for transporting and pumping fibrous suspensions of cellulose from softwood. The main stages of modeling of pumping equipment used in the pulp and paper and chemical industries are considered. Hydrodynamic processes occurring in the working part of a centrifugal pump are investigated. Currently, the development of flow parts of modern centrifugal pumps necessarily includes a stage of hydrodynamic computer simulation of the fluid flow in order to optimize the design and increase efficiency. This will increase the efficiency of the device, reduce the cost of its design and operation, and increase the cavitation reserve of the pump. Without such optimization, through software modeling, the unit in most cases will require incomparably high costs for conducting a series of tests to bring the geometry of the flow part to an acceptable level. Of course, conducting model and full-scale tests is mandatory for verifying the results of numerical modeling, but as the final stage of creating the device. This design algorithm allows you to save time and money for developers, as well as raise the overall technical level of pumping equipment.
