Description

Turbomachines are used in many technical fields, from water and gas turbines for energy generation, fuel pumps and fans in cars, aircraft propulsion systems and heart and blood pumps in the human body.

This training teaches the fundamentals of the design and optimization of aerodynamics and hydraulics with the aid of numerical methods (CFD – Computational Fluid Dynamics). After an introduction to the theory, we demonstrate the practical use of software tools for radial and axial flow machines. At the end of the course you will know what to look for when assessing results and how to draw informative conclusions from your simulations.

The training course is aimed at project managers, development, and simulation engineers as well as researchers who want to develop, optimize or use turbomachines in their products and simulate them using numerical methods.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

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.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

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).
