Using Detailed Chemistry in Ansys Chemkin-Pro for More Accurate CFD Combustion and Reacting Flow Simulations

Computational fluid dynamics (CFD) can help designers achieve higher performance and lower emissions for combustion and reacting flow systems — without costly physical prototyping. But combustion CFD can only be of value if the simulations predict real-life behaviors

GEKO Puts You in Control of CFD Turbulence Modeling

Because no single turbulence model is suitable for all flow applications, users have had to choose from a finite set of fixed models, hoping that one fits their simulation. With the introduction of GEKO (generalized k-omega) — a revolutionary innovation in turbulence modeling within ANSYS Fluent — users have the flexibility to tailor turbulence models to their applications. GEKO provides several free and tunable parameters that can be adjusted over a wide range to match the simulation to specific physical effects, while maintaining the underlying calibration for flat plates and mixing layers

Using Simulation to Optimize Reacting Flows and Combustion – Application Brief

From automobile engines to gas turbine generators to fab tools, reacting flow and combustion is often the key to energy efficiency, emissions, lifespan, product yield, and other performance parameters. Simulation can help your engineering team look deeper into reacting flow and combustion issues to understand the complex chemical reactions, fluid flow, heat transfer, electrical performance, and other factors that determine the performance of your product. Simulation enables your engineers to evaluate more design alternatives more thoroughly than traditional prototype-based design and development methods.

Ansys LS-DYNA Smooth Particle Hydrodynamics

Smooth particle hydrodynamics (SPH) is a Lagrangian particle method for modeling impacts, explosions or fluid–structure interaction (FSI) problems. The method was developed to avoid the limitations of mesh entangling encountered with the finite element method in extreme deformation problems, and to model complex free surface and material interface behaviors, including solid fragmentation. The SPH method in Ansys LS-DYNA® is coupled with the finite and discrete element methods, extending its range of applications to a variety of complex problems involving multiphysics.

Ansys Advantage Issue 2 2019

To leverage pervasive engineering simulation, every engineer must have access to simulation throughout design, testing and operation processes. To do this effectively means eliminating bottlenecks. Recent advances in computational fluid dynamics have reduced these bottlenecks for engineers, whether they are recent graduates or world-class simulations experts. This issue of Ansys Advantage describes these advances and reveals how organizations around the world benefit from this technology.
