Zusammenfassung

Dieses Kapitel ist den numerischen Verfahren zur Lösung der im vorigen Kapitel vorgestellten Navier-Stokes Gleichungen gewidmet. Der Schwerpunkt wird auf Finite-Volumen-Verfahren gelegt, die üblicherweise in motorischen CFD-Codes zum Einsatz kommen. Neben dem numerischen Schema spielt insbesondere das Berechnungsnetz eine Schlüsselrolle, was anhand verschiedener Beispiele diskutiert wird. Abgeschlossen wird das Kapitel mit der direkten Numerik-Simulation der Strömung im Brennraum, die aufgrund besonders hoher räumlicher und zeitlicher Auflösung ohne Modellierung der Turbulenz auskommt.

Notes

  1. 1.

    Die Größe \(\text{Pe} = v\Updelta x/D\) nennt man auch Peclet‐Zahl.

  2. 2.

    θ(x) bezeichnet die Heaviside‐Funktion: \( \theta (x) = \begin{cases} +1 & x \geq 0 \\ -1 & x < 0 \end{cases}\).
