Multiphase Flow with Ansys Fluent
Learn how to simulate flows that involve bubbles, droplets, particles and free surfaces. This training is offered as a 3-day course or alternatively as a self-paced eLearning course.
Duration
3 days
Prerequisites
Basic knowledge of Ansys Fluent
Software used
Ansys CFD
- Acquire the basics of multiphase flow simulations
- Overview of the available models and methods for model selection
- Learn solution strategies and setup of practical problems
- Workshops for various classes of multiphase flows
Description
Engineers dealing with multiphase flows know that these are prevalent in natural and industrial processes. The challenge is to decide whether to model the interphase-boundaries in detail or to consider a macroscopic behavior of the disperse phase. Regardless of whether it is a bubble, droplet, or solid particle, Ansys Fluent offers a variety of models for multi-phase CFD.
Setting up a simulation model in Ansys Fluent requires both theoretical knowledge and practical experience. In this training, you will receive a compact overview of the various models and tips for selecting suitable approaches for your problem. Since the modeling approaches for multiphase flows are diverse, we work with several practical examples for illustration.
CFD users in areas such as process engineering, mixing technology, filling processes, shipbuilding, hydraulic engineering, environmental engineering, pharmaceutical industry, filter technology, plant engineering, or oil and gas industry can benefit from the application of these models. You will learn to use Ansys Fluent independently for the successful simulation of multiphase flows.

Get a first impression and test the first eLearning module of this training course without any obligation. No costs, no notice period.
Whether eLearning, classroom courses, live online training or customized workshops - together we identify the best option for you.
Do you have questions on the training or the eLearning?
If you book through your university, you will receive a 50% discount on the stated fee on training courses and eLearning courses.
For more information on the validity and how booking with the code ACADEMIC50 works, please visit our page on training for academic users.
Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.
As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.
If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.
Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.
Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.
Prerequisite for the use of the eLearning courses is the use of a personalized access to the CADFEM learning platform. When purchasing an eLearning course, access to the learning platform is 365 days. As a subscription user, access to the learning platform starts and ends with the start and end of the flat rate. With the start of a further learning product (Learning Subscription, training, eLearning), access to your content is extended by 365 days.
