PERMAS workshop Heat Transfer (German) (HT)
Linear and nonlinear methods for steady-state and transient heat transfer analysis
In PERMAS there are several solution methods for the analysis of temperature fields available. These allow the solution of stationary and transient problems in the linear and non-linear area.
The training gives the participants an overview of the available procedures and also some aids in order to make a decision when which procedure should be used.
The model structure, the data input in PERMAS as well as the UCI commands for the controlling of the solution methods are in the foreground of this training.
In addition, the participants receive important information and hints from practice which make it much easier to apply them to their own models.
The training also addresses coupled analyses. It will be shown how a thermomechanical analysis is performed with PERMAS. With this type of analysis, the calculated temperature field is applied as a load in a subsequent static analysis. This can be done either within a single PERMAS calculation or in several successive calculations.
Another focus of the training is on the topic of heat exchange through radiation. This is
important for components with cavities that are exposed to very high temperatures, such as brake systems, combustion engines or cooler. In this case, PERMAS first determines the visibility factors of the surfaces involved and then, in a non-linear analysis, the exchanged heat flows and the temperature field in the components.
The aim of the training is that the participants learn how to calculate the heat transfer through radiation and convection on the component surface, coupled with heat transfer in the
structure.
Application examples and own exercises deepen the training subject.
