Summary |
---|
The course is focused on the possibility of modeling the flow of heat transfer (conduction, convection), including the generation of mesh for issues related to the modeling of flow. Students will extend theoretical knowledge in the field transfer of heat, mass and momentum of flow. The finite volume method (FVM) will be used to solve the system of equations describing the flow. The method will focus mainly on the solution of conduction of heat by various construction structures, which will be defined by different material properties. Furthermore, (FVM) will be applied to the issue of air flow in a closed room and thus the solution of air conditioning. ANSYS-Fluent software is used for practical applications of the example (FVM). Numerical simulations will be realized on BIM models within the course. To adjust of geometry in software ANSYS will be used DesignModeler and ANSYS Meshing is used to generation of mesh. |
Learning Outcomes of the Course Unit |
---|
Students will learn the mathematical model of fluid flow including heat transfer by conduction and convection using the finite volume method (FVM). They will be able to create a mathematical model of heat transfer through different construction structures, which will be characterized by materials with different physical properties and the problem subsequently solved. Furthermore, students will be able to define the mathematical model of turbulent flow and apply it to the problems of ventilation in a room, building or production hall. |
