SimuTech Group is a North American leader in reacting flow and combustion analysis consulting, with projects ranging from chemical vapor deposition (CVD), dynamic simulation of multistage reactors, flow regulation into rotary fiberizers, modeling advective and diffusive transportation of different chemical species and the resulting mixings, and more.
There are now technologies and accompanied processes available for businesses to reliably simulate chemically reactive fluids. Designing innovative new technologies that are revolutionizing the way we live requires the use of contemporary engineering techniques.
Due to lengthy lead times and expensive costs of physical prototypes, trial-and-error oriented methods to building reactive flow systems is seen as impracticable for most businesses (are rightfully so).
However, digital models are currently being utilized to investigate novel chemical reactions and test ideas under various design constraints, at a fraction of the traditional expenses accompanied.
Our custom configuration, with Ansys as the foundation software, allows our engineers to model detailed complete chemical reactions with its Reaction Design CHEMKIN chemistry solver.
Physical chemistry and fluid dynamics are combined in chemically reacting flows, which are frequently seen in both industry and daily life.
Fluidized bed reactors, gas turbine combustors, methane reformers, glass furnaces, solid fuel furnaces, biofuel generation, fermentation, and building fires are examples of industrial use cases.
Future winners and losers in these industries will be determined by the ongoing innovation of current items and the launch of new and inventive products, made possible by digital simulation.
Complex geometry and physics, such as numerous phases, conjugate heat transfer, radiation, and turbulence, are frequently present in chemically reacting systems.
This complexity necessitates a focus on speed without compromising accuracy. Through a broad collection of reactive flow models and numerical techniques, cutting-edge meshing algorithms, and automated workflows, our preferred program, Ansys Chemkin Pro, excels in this regard.
Intricate chemistry models for accurate species predictions, flamelet models for quick and precise flame-front predictions, and chemical equilibrium models for the quickest forecasts are some of the specific techniques we frequently employ. We have experience with specialized models, such as those used to forecast emissions like CO, GHG, AZLH, AALH, ARLH, AMLH and NOx, as well as adaptive meshing for improved accuracy.
In addition, our simulations routinely include impacts of radiation and environmental variables together with conjugate heat transfer through nearby solids.
Modeled the combustion process in a mixing rate limited transient multiphase reaction 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.
Using the principles of established fluid flow, CFD forecasting determined aerodynamic and hydraulic performance inside and outside of a high-rise structure.
Modeled the multispecies thermal flow of supercritical water and cold hydrocarbons through a series of mixing tees, reactors, and heat exchangers.
Coupling the detailed flow field and chemistry, complex real-world reactions/combustion problems can now be accurately modeled, even up to thousands of chemical reactions, allowing the prediction of even minor chemical species in complex real geometries.
