Numerical Simulation

Temperature distribution on the structure surface during a thermally coupled fluid-structure-interaction simulation

The numerics group is engaged in the development and application of methods for the numerical solution of the basic fluid flow equations. Among the core research topics are finite volume methods for flows in complex geometries, fluid-structure-interaction problems, implementation and validation of turbulence models, large eddy simulations, multiphase flows and flows with phase transitions. The developed numerical methods are applied to the investigation of basic physical phenomena as well as to the solution of real-world problems, where the combination of simulations and experiments allows for significant reduction in both development time and cost. Using the high performance computing capabilities of the local computing center (RRZE), the simulation of
complex flows comes within reach, giving the possibility to obtain a holistic image of the flow under consideration, that could not be achieved using measurements alone.

Der jährliche europäische Kunststoffverbrauch lag 2016 bei 50 Mio. Tonnen (40 % Verpackungen). Um einen schonenden Umgang mit unseren natürlichen Ressourcen zu gewährleisten, besteht ein vielversprechender Ansatz in der Minimierung des notwendigen Materialeinsatzes bei gleichbleibender Funktionalität. Ein häufig eingesetztes Verfahren, z.B. zur Herstellung von Verpackungen ist das Thermoformen. Mit Hilfe des Thermoformens können insbesondere dünnwandige Formteile hergestellt werden,…

Ein weit verbreitetes, kostengünstiges Herstellungsverfahren von dreidimensionalen Kunststoffformkörpern aus planen Halbzeug ist das Thermoformen. Es dient der Fertigung von technischen Bauteilen sowie Verpackungen. Nicht zuletzt aufgrund des hohen Ressourcenbedarfs für Verpackungen (70 % des weltweiten Kunststoffverbrauchs), besteht aus ökonomischen und ökologischen Aspekten ein stetiger Bedarf nach materialsparenden Technologien und Verfahren.

Im Zuge des Thermoformenprozesses wird…

Among the currently or recently studied topics there are:

bubble flows
coating processes
convergence speed-up in fluid-structure-interaction simulations
fluid-structure-interaction: in turbulent flows, with thermal coupling or involving thin wall elements
flows with heat transfer
methods for high performance computing
development and implementation of the in-house code FASTEST-3D (Finite Volumes)
iterative geometry optimizationflows wit phase transitions

The most prominent discretization method for the governing equations of fluid flow in proprietary as well as freely available CFD codes is the finite volume method. Hence, this is also the commonly applied methods within the numerics group. At this, the current state of the art commercial flow solvers as well as the in-house code FASTEST-3D is used for the numerical prediction of fluid flows.

In addition, the group has expertise in the application of finite difference, finite element, and lattice-boltzmann methods. Due to years of experience with the development and application of turbulence models, a realistic assessment and simulation even of complex turbulent flows becomes possible.

In cooperation with other research groups from the institute or other research centers, experimental investigations can be conducted for the validation of the simulation results.
