To optimize the fuel consumption, new concepts like the Thermo Electric Generator (TEG) may show potential. To analyze the possibilities of such system, the layout can be modeled in KULI and different concepts can be compared.
The model consists of an exhaust gas system (hot side) and a water circuit (cold side), whereby the electric power is generated out of this temperature difference.
The modeling of new concept like the TEG is a challenging task for each engineer. This example shows how such a model can be easily created with KULI “on-board” components.
Therefore a combination of calculation controllers, maps and circuits is used to describe the behavior of such a component.
Basically the model consists of two circuits, whereby each of them contains a point mass (hot and cold side of the TEG). Both PM are connected by heat conduction, the area for the heat transfer is calculated by the overall number of elements, the area of such an element and the thickness.
For the calculation of the TEGs performance, the characteristic is provided by a 2D curve which is based on the temperature difference between hot and cold side.Usable from release: KULI 9.1-0.01
