Computational Fluid Dynamics (CFD)
ANSYS offers a comprehensive suite of computational fluid dynamics (CFD) simulation software products that allow you to determine the impact of fluid flows on your product. Whether you are a design engineer or an analyst, ANSYS has a product that will provide you with unparalleled fluid flow analysis capabilities. Whatever fluid flow phenomena you are studying, ANSYS’ fluid dynamics solutions can give you valuable insight into your product’s performance.
ANSYS fluid dynamics solutions are fully integrated into the ANSYS Workbench platform. This environment delivers high productivity and easy-to-use workflows. Workbench integrates all your fluid workflow needs (pre-processing, simulation, and post-processing) as well as multiphysics functionality (fluid–structure interaction (FSI), electromagnetic/fluid coupling, etc.) into one easy to use interface. Additionally, via Workbench, you gain the ability to perform automated design optimization studies.
As always, feel free to contact us at anytime if you would like assistance in determining the right product for you! Below is some additional information about each of the products and capabilities of the software.
Cavitation happens when vapor bubbles form in a liquid because flow dynamics cause the local static pressure to drop below the vapor pressure. Without accurate prediction of cavitation, users cannot effectively optimize designs and set operating parameters and limits, potentially exposing their products to unexpected vibration and damage.
Fluid flow exerts pressure on solid objects and deforms them. That deformation can, in return, impact the fluid flow around the object. ANSYS multiphysics accurately captures the interplay of these forces so you can optimize your product’s performance.
Engineers need to optimize processes such as extrusion, thermoforming, blow molding, glass forming, fiber drawing and concrete shaping. CFD accelerates design while shrinking energy and raw material demands to make your manufacturing processes more cost-effective and environmentally sustainable.
ANSYS HPC enables CFD engineers to better simulate product performance and integrity in less time. In addition to efficiently scaling CFD solvers to over 129,000 cores, ANSYS has been investing heavily to ensure the entire CFD process, from prep to meshing to post-processing, are all taking advantage of HPC to speed the total time to solution.
Chances are that your fluids simulation includes multiphase flows like boiling, cavitation, dispersed multiphase flows, immiscible flows and flows with particulates. ANSYS CFD provides the widest range of sophisticated turbulence and physical models to accurately simulate the toughest challenges so you can confidently predict your product’s performance.
Engineers use ANSYS CFD simulation to design lower-emission combustion systems without spending millions of dollars on physical mockups and costly trial-and-error testing. Accurately predicting real-life fuel effects requires complex algorithms that describe the physics and thermodynamic behavior of combustion, a detailed understanding of the chemical makeup of the fuels to be burned and types of engine to be deployed.
Instead of guessing geometry parameters and simulating hundreds of design points, ANSYS smart shape optimization tools give fast, specific insight into finding the ideal solutions for problems such as reducing pressure drop, optimizing drag, lift or heat transfer. For example, the ANSYS Adjoint Solver recommends and even automatically implements design enhancements, morphs the mesh to a more optimal shape and predicts the performance improvement.
In-flight icing is a highly complex physical phenomenon that is extremely difficult and expensive to model with physical testing. Regulatory changes and industry focus on the particular hazards presented by high-altitude ice crystals and supercooled large droplets have further challenged the design process and the time to market for new aircraft and technology. ANSYS FENSAP-ICE provides state-of-the-art, 3-D design and aid-to-certification solutions.
Single phase, non reacting flows are found in wide-ranging applications from automobile and aircraft external aerodynamics to aero-acoustic noise and submarine propellers. These flows could include heat transfer and be steady or unsteady, but do not include phase changes or reactions. ANSYS CFD accurately models real world flows including turbulence. More importantly, ANSYS tells you when single phase flows become multiphase, for example with cavitation.
Devices need to optimize heat transfer between fluids and solids to maintain a constant temperature and maximize performance, reduce maintenance costs and extend the life of the machine. Fluids can cool and heat machine parts, process equipment, engine components and other solids. These thermal effects can in turn deform the walls or parts that are being cooled or heated. ANSYS delivers fast and accurate solutions to predict performance for the widest range of fluid-solid heat transfer problems, including conjugate heat transfer (CHT) and thermal fluid–structure interaction (FSI).
Turbomachinery is the most rewarding and the most challenging of simulations. ANSYS delivers innovations at every stage of the simulation process, from modeling to meshing, solving to post-processing. Whether designing a jet engine, wind turbine or turbocharger, ANSYS helps you to extend the limits of what is possible so you can maximize your product’s performance and efficiency.
There is no single best turbulence model. Learn how turbulence model selection can impact simulation accuracy — even for seemingly simple applications. Turbulence is a critical computational fluid dynamics (CFD) app that you must get right.
