AbstractAnalysis of detailed chemical reactions of combustion sometimes requires the handling of hundreds to thousands of chemical species, and often involves very fast reactions. In the calculation combining CFD and such a chemical reaction, most of the total calculation time is occupied by chemical reaction calculation. In this paper, we propose a new method using a simple implicit method and time step decision method. Although this method requires inner iteration, it fulfills high speed and conservation law completely. We will show the formulation of the new scheme, then its effectiveness and accuracy will be shown using 0-D premixed ignition and 1-D laminar flame.
