Ansys KINetics API operates with Ansys Chemkin, which is the market leader for microkinetic and detailed kinetics modeling of gas and gas-solid systems. Detailed chemical kinetic mechanisms describe the chemical behaviors in detail, and can involve elementary reactions, where reactions represent molecular interactions and the breaking and forming of chemical bonds. Consequently, these mechanisms have good versatility and the reaction rate for a particular chemical interaction can be used in any reaction mechanism that contains the participant species. Detailed mechanisms aim to describe the chemical behaviors in the greatest detail possible and therefore generally have good versatility; the reaction rates have good portability to other detailed mechanisms. In contrast, skeletal mechanisms / global kinetics are usually developed for specific conditions.

Ansys Chemkin software is used both to develop detailed mechanisms and to predict the performance of the chemistry in pre-defined flow conditions (for example, well-mixed regions, plug flows, channel flows, and others). Ansys KINetics API™ provides an easy way to integrate the core capabilities of Chemkin simulation into computational fluid dynamics (CFD) software for addressing reacting flows in arbitrary geometries. KINetics API features proprietary solver components that allow fast and robust simulations for transient and steady-state calculations. These solvers are tailored to enable efficient chemistry solution within CFD simulations.

This document provides reference material about the KINetics API.
