ANSYS Computational Fluid Dynamics (CFD)
Computational Fluid Dynamics (CFD) is a tool with amazing flexibility, accuracy and breadth of application. But serious CFD, the kind that provides insights to help you optimize your designs, could be out of reach unless you choose your software carefully. To get serious CFD results, you need serious software. ANSYS CFD goes beyond qualitative results to deliver accurate quantitative predictions of fluid interactions and trade-offs. These insights reveal unexpected opportunities for your product— opportunities that even experienced engineering analysts can otherwise miss.
Applications
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 a world record 172,000 cores, ANSYS has been investing heavily to ensure the entire CFD process, from prep to meshing to post-processing, is taking advantage of HPC to accelerate 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.
Understanding and predicting the effects of reacting flows is critical to developing competitive products in diverse industries such as transportation, energy generation and materials processing. Knowing the underlying chemistry and physics enables designers of gas turbines, boilers and IC engines to increase energy efficiency and fuel flexibility and reduce emissions. Similarly, designers of high-throughput materials and chemical processes need high yields and quality, along with minimum byproducts and waste. A thorough grasp of the underlying physics and chemistry is also critical to making improvements in lithium-ion batteries, fuel cells and many other products.
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.
