CFD Reacting Flows & Combustion
In order to accurately model combustion, it is important to account for the interactions between turbulence, mixing, and chemical reactions. Turbulence models are used to capture the turbulent flow behavior of the fuel and oxidizer mixture, while mixing models are used to predict the mixing of fuel and oxidizer. Chemical kinetics models are used to describe the chemical reactions that take place during combustion, including the rate at which reactants are consumed and products are formed.

The use of detailed chemistry in combustion simulations allows for the prediction of species concentrations and temperature profiles throughout the combustion process. This can help to optimize combustion systems for improved energy efficiency and reduced emissions. For example, detailed chemistry simulations can be used to predict the formation of pollutants and other undesirable combustion byproducts, and to evaluate the effectiveness of different combustion control strategies. We use advantage of CFD solvers detailed chemistry, multiphase flow modeling, and other powerful features of CFD softwares(Siemens Star-ccm+, AVL Fire, Ansys Fluent, Converge).
The wider discipline

Reacting Flows & Combustion

Combustion is a complex process that involves the interaction of fluid dynamics, thermodynamics, and chemical kinetics. In order to design efficient combustion systems, it is important to understand the underlying physics and chemistry of the process. Reacting flows and combustion simulations can be used to model and predict the behavior of combustion systems under different conditions.

Reacting flows refer to fluid flows that involve chemical reactions. Combustion is a typical example of a reacting flow, where fuel and oxidizer are mixed together and ignite to release heat energy. Combustion simulations …
