Abstract: В статье приведена методика создания математической модели для решения внутренней гидродинамической задачи в прикладном программном пакете Solid works. Рассмотрены основные возможности пакета для моделирования объектов химической технологии. Исследованы гидродинамические эффекты, возникающие в результате прохождения жидкости через конфузорно-диффузорное устройство.
Description: The article describes a method of creating a mathematical model for the solution of the internal hydrodynamic problem. The most common problem faced by the specialists of Chemical Technology profile is the internal hydrodynamic problem. This problem is understood as the study of fluid flow, surrounded by solid walls. As a particular case is an example of the flow of fluid through the orifice - diaphragms, nozzles, Venturі tube. Affirms, that the possibility of an empirical research is inconvenient to the majority of objects of the chemical industry in view of complexity, high speed, explosion and fire danger of processes proceeding in them. It is concluded that the theoretical study of such facilities is preferred. It is proposed to study the internal hydrodynamic problem by computer simulation. As a tool of research selected application software package and its module for simulation of hydrodynamic processes based on the technology of computer fluid dynamics (CFD). The description of stage-by-stage creation of computer model is given: creation of solid-state model of considered object, creation of the project of research, the task of boundary conditions of modeling, the task of goals of the project. The description of start and carrying out of calculation of the created hydrodynamic model of studied object is resulted. Recommendations for modeling objects of chemical technology are resulted.. The results received during modeling are given in the form of charts of distribution of the basic hydrodynamic parameters: speed and static pressure on longitudinal axis of the object. Variation of these parameters does not contradict theoretical concepts about behavior of a liquid and gases at their movement in the limited spaces. Conclusions about prospect of use computing CFD packages for the decision of research problems of chemical technology are given. The conclusion that their use will allow to reduce essentially expenses of time at stages of studying, designs and introductions new and intensifications of already used chemical process processes is done.
