Summary: | In practice there are many processes that have complicated and complex character. Most often, these are dynamic systems with a large number of variable parameters, which significantly complicates their study, analysis and prediction. For their study most commonly used simulations that allow you to gain knowledge of their systemic nature. In these systems include and the thermodynamic systems where, due to a change of the many influencing parameters: temperature, pressure, velocity, fluid flow rate, various physical processes take place. For their study is widely used computer simulations to help predict the behaviour of systems under various conditions. Simulations are closely related to direct geometric modelling to enable to interactive design research and rapid model creation, allowing engineers to experiment with design ideas and immediately see the result of their changes. As an object of the simulation is most often fluid, structural and thermal simulation applications, which are used both for research and for innovative practical solutions in manufacturing enterprises. Computer simulations allow to predict the behaviour of certain processes in a real environment through virtual testing of CAD models. The main stages contain a methodical sequence, which includes the construction of a mathematical model, its numerical solution and processing of the obtained results. The main equations that make up the mathematical models are the balance equations of mass, momentum and energy, which determine the distribution of velocities, pressures, densities, temperatures and other control parameters. For modelling of flows of liquids and gases for industrial tasks, turbulence, heat transfer and chemical reactions, etc. are taken into account. In the practice, a large number of software solutions to simulate the processes occurring in thermal and fluid flows offered by many manufacturing companies are used. The aim of the present study is to analyse the possibilities of the software products used in practice to simulate the behaviour of dynamic fluid flows under certain initial conditions. Based on the analysis and the formulated conclusions, the choice of a software module for specific thermal research and construction of a geometric model of the studied objects through which numerical (CFD) simulations will be performed using different models, research in different modes of work, as well as the validation of the created methodologies, will be substantiated. |
