Capture the complex interplay of turbulence, heat transfer, and chemical kinetics with reacting flow CFD — essential for accurate modeling of combustion, catalysis, electrochemical systems, and CVD processes.
Reacting flow computational fluid dynamics (CFD) is a specialized area within fluid dynamics that focuses on the simulation of flows including chemical reactions. This involves the combined simulation of fluid flow, heat transfer, and chemical reactions. Some types of reacting flows are Combustion, Catalysis Reactions, Electrochemical Reactions, and Chemical Vapor Deposition (CVD).
Reacting flows often involve numerous species and reactions, requiring detailed chemical kinetics, or reaction rate, models. Accurately capturing the interaction between turbulent flow structures and chemical reactions is challenging but important for accurately modeling reacting flows.
The combustion process involves complex chemical reactions. Detailed chemical kinetic mechanisms describe these reactions, including the formation and consumption of various species (reactants, intermediates, and products).
Combustion generates heat, and its transfer affects the temperature distribution within the system. This heat transfer includes conduction, convection, and radiation.
Ansys Fluent and Ansys Chemkin offer a comprehensive software suite with capabilities for modeling reacting flows including combustion, such as:
Modeled the combustion process of hydrogen, methane, and the blend in a multiphase combustion chamber to calculate the heat production of the chamber.
Modeled the detailed chemistry of the CVD process which included the detailed surface chemistry. The resulting deposition rate and uniformity was predicted for a given chemical vapor deposition chamber.
Performed thrust and flow analysis of a space shuttle rocket engine combustion chamber with steering from eccentric rod application.
Predicted the temperature and velocity profiles at the exit of the combustion chamber for a rotary fiberizer process. The model used the fast chemistry model and solver to include all the required chemical mechanisms.
Modeled the multispecies thermal flow through a series of mixing tees, reactors, and heat exchangers.
Some examples of reacting flow and combustion include chemical reactors and reformers, internal combustion engines, gas turbines, industrial furnaces and boilers (glass furnaces, solid fuel furnaces, biofuel generation), aerospace propulsion, and fire safety.
