Numerical Simulation of Laminar and Turbulent Methane/Air Flames Based on a DRG-Derived Skeletal Mechanism
TL;DR: In this paper, a DRG-derived skeletal mechanism was developed using only one application for methane/air simulations and validated for auto-ignition times, laminar flame speed and counterflow flames.
Inluence of cutting parameters, tool coatings and friction on the process heat in cutting processes and phase transformations in workpiece surface layers* Einluss von Schnittparametern, Werkzeugbeschichtungen und Reibung auf die Zerspantemperaturen und Gefügeumwandlungen in Bauteilrandschichten

TL;DR: Kurzfassung et al. as discussed by the authors presented a 2D-FE-cutting simulation model predicting machining induced phase transformations of workpiece surface layers for the steel 42CrMo4 (AISI 4140) considering detailed friction modeling between tool and workpiece, based on tribological experiments.
Fast–slow vector fields of reaction–diffusion systems
TL;DR: In this paper, a geometrically invariant concept of fast-slow vector fields perturbed by transport terms (describing molecular diffusion processes) is proposed, which is an extension of our concept of singularly perturbed vector fields to reaction-diffusion systems.

- 01 Jan 2007
TL;DR: In this article, two transported PDF strategies (joint velocity-scalar and joint scalar PDF) are investigated for bluff-body stabilised turbulent diffusion flames with variable degree of turbulence chemistry interaction.
Simulation von Zündung und Verbrennung
Jürgen Waniatz,Ulrich Maas +1 more
TL;DR: Verbrennungsprozesse beruhen auf einem komplizierten Wechselspiel von Stromung, Transportprozessen und chemischen Reaktionen as mentioned in this paper.
