Gedanken flame experiment

Gedanken Flame Experiment. In order to illustrate how the problems caused by the requirements of temporal and spatial resolution and geometric and physical complexity are translated into computational cost, we have chosen to analyze a gedanken flame experiment. Consider a closed tube one meter long which contains a combustible gas mixture. We wish to calculate how the physical properties such as temperature, species densities, and position of the flame front change after the mixture is ignited at one end. The burning gas can be described, we assume, by a chemical kinetics reaction rate scheme which involves some tens of species and hundreds of chemical reactions, some of which are "stiff."...

Using the information discussed so far, we can now return to the gedanken flame experiment with the idea of considering modified numerical methods in order to reduce the computational cost. The goal is to calculate the propagation of a flame front across a one-meter tube using a one-dimensional geometry with a fixed detailed chemical reaction rate scheme.
