Reacting Flows

Reacting flow is made up of powerful features that allow you to build a custom solution. Read more about these features below.

Simcenter delivers a comprehensive suite of reacting flow and emission models, covering a wide range of applications. It enables tight coupling between reacting flow models and heat transfer, radiation, multiphase reactions, and surface chemistry. Our reacting flow models help understand and optimize flame shape and location, minimize solid component temperatures, reduce emissions and maximize performance efficiency. You can predict and understand flame dynamics, heat transfer, thermal wear, emissions, yield, conversion, selectivity, and undesirable conditions to accurately capture real-world physics of your designs.

Flamelet Models

Reduce computational expense by approximating combustion chemistry using a 0D/1D laminar flamelet. Utilize accurate flamelet generated manifold through inclusion of heat loss effects on species composition, accurate combustion table generation and accurate flame location by combining with propagation models.

Multiphase & Surface Reactions

Tight coupling between reacting flow models and flow, heat transfer, radiation and multiphase models ensures engineers are always simulating accurate physics. Multiphase reactions work with eulerian multiphase and VOF models for bubble columns, metallurgy, trickle bed reactors and fluidized beds. Surface reactions extend applicability to CVD, catalytic reactions in aftertreatment and methane formation while particle reactions are used to model coal and biomass combustion.

Reacting Species Transport Models

Choose from a generalized approach applicable to gas phase combustion and liquid-liquid reactions with chemistry modeled in 3D CFD with all species transported and reactions calculated online. These four models – complex chemistry, eddy break-up, eddy contact micro-mixing and polymerization – are applicable for multi-stream combustion and calculation of slowly forming pollutants, ignition and extinction.

Reaction & Combustion Models

Simcenter offers a wide range of industry-relevant models for Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES) scenarios for modeling reaction and combustion. Use the appropriate model for accurate species prediction through complex chemistry, accurate and fast flame location prediction and higher-order methods for LES combustion.

Specialized Models

Simcenter offers specialized models to accurately simulate emissions like NOx, soot, CO and HC, ignition and re-light in gas turbines, furnaces, burners, and steady-state combustion and also reacting channel models for process heaters, cracking furnaces and steam reformers.
