Reaction & Combustion CFD Simulation

Computational Fluid Dynamics (CFD) can be used to simulate flows in which combustion reactions occur. Combustion analyses are amongst the most demanding of CFD applications with: multiple chemical species, multiphase flow and particle tracking (depending on fuel type), chemical reactions, turbulent reacting flows, combustion models and the large corresponding complex release of heat. A wide range of industrial analysis applications exist such as: combustors, engines, furnaces, burners and heaters. Combustion models can be defined with both single and multiple reaction steps during the combustion process. Typical objectives of these project analyses have been:

• Prediction of performance and optimisation.
• Calculation of the temperature fields and heat transfer rates (convection and radiation) resulting from combustion and design adjustments to improve uniformity.
• Visualisation of the ‘flame zone’ and predicted corresponding flow phenomena.
• Quantification of the resultant downstream pressure loss.
• Evaluation of mixed species distributions, composition and properties of the burnt mixture.
• Reacting flow analysis.
• Combustion flow analysis.
