Computational Fluid Dynamics (CFD) in Systems Simulation

In system simulation, the behavior and interaction of technical devices is described by means of mathematical relationships. Interdisciplinary couplings which take into account the influences of the physical behavior of the individual components of a device or component are also used. The mathematical description of the behavior of the individual components is established by means of characteristic variables and variable course over time as well as over various stress profiles.

In practice, software products are used to simulate the interaction of the various physical disciplines in which these laws can be mathematically described. These are, as a rule, object-oriented model description languages, in which the physical processes described, are transferred to mathematical models and then solved. This enables you to get the first insights into how new product concepts behave during the early phase of the product development process. This information is again integrated into the CAE process. 

Of great importance is the use of system simulation for the efficient development of complete fluid flow systems, eg in the automotive industry. In this form of system simulation CFD can be considered in various forms. These are 0D and 1D models, which represent the fluidic behavior of components as a mathematical description of, for example, temporal parameters. These models and their results are then used as boundary conditions in the two- or three-dimensional representation of individual components or components, in order to simulate the detailed behavior.

With modern software products, these methods can be coupled in such a way that parameter analysis is also made possible in order to identify weak points in the system at an early stage, as well as to optimize the entire system or individual components.

In this seminar, methods for the system simulation of fluid mechanics problems are presented, as can be deduced from the overall behavior on the behavior of individual components and vice versa
