Fluids - Computational Fluid Dynamics
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, can 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 miss.

FIVE CRITICAL CFD APPS
As products push the performance envelope, they may not behave as expected. As a result, more engineers are relying on simulations to optimize performance. But are they accurate? Here are five common CFD . . .
Battery Simulation
Chemistry, electricity and thermal management of batteries operate in a complex interplay that must be controlled within narrow margins to ensure long battery life and low cost. The slightest deviations from these . .
CAVITATION
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 . .
ELECTRIC MOTOR COOLING
For electrical components to be reliable and efficient, temperatures must be monitored and maintained within tight parameters. In electric motors, during the process of converting electrical energy to mechanical energy,
Fluid-Structure Interaction
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 .
RHEOLOGY
ANSYS Polyflow provides advanced technology for companies in the polymer, glass, metals and cement processing industries. R&D teams use this technology extensively to design and optimize processes such as . .
HPC – FLUIDS
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.
Multiphase Flows
Chances are that your fluids simulation includes multiphase flows like boiling, cavitation, dispersed multiphase flows, immiscible flows and flows with particulates.
Reacting Flows and Combustion
Understanding and predicting the effects of reacting flows and combustion chemistry are critical to developing competitive products in the transportation, energy generation and materials processing industries,
REDUCED-ORDER MODELS
Reduced-order models (ROM’s) can accelerate your simulation time without sacrificing accuracy compared with a full 3D simulation. ROMs are simplified versions of a model that preserve essential behavior and dominant ..
SHAPE OPTIMIZATION
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.
SIMULATING AIRCRAFT ICING
In-flight icing is a highly complex physical phenomenon that is extremely difficult and expensive to model with physical testing.
SINGLE PHASE, NON-REACTING FLOWS
Single phase, non-reacting flows are found in wide-ranging applications from automobile and aircraft external aerodynamics to aero-acoustic noise and submarine propellers.
THERMAL MANAGEMENT
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.
Turbomachinery
Optimizing the design of rotating machinery such as compressors, turbines, pumps, fans, blowers, turbochargers and turbopumps offers enormous potential.
Turbulence Modeling for CFD Simulation
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.
