A comprehensive understanding of combustion processes is now possible using computational fluid dynamics (CFD), but only if the underlying chemistry of combustion is taken fully into account. With 60 fuel components reacting via complex chemical mechanisms in short time intervals, knowledge of which components react in which order is essential to successful, robust combustion modeling. Recognizing this, Ansys has incorporated the most comprehensive, validated fuels chemistry database ever assembled — The Model Fuels Library — included with Ansys Chemkin Enterprise, Ansys CFD Enterprise, and Ansys CFD Premium to design more cost-effective, efficient, cleaner burning engines. In addition to proving that chemistry really does matter, Ansys Forte simulations have demonstrated other important facts: combustion CFD modeling can be both fast and accurate by using sparse-matrix technologies; soot formation can be modeled by following soot precursors through the nucleation, growth, agglomeration and oxidation stages; and engine knock can be simulated using advanced, proven mathematical techniques and algorithms. |
