Bronswerk Heat Transfer, a manufacturer of heat exchangers and fans, has expanded use of Flomerics' EFD.Pro from strictly research and development to everyday engineering design.

Bronswerk Heat Transfer, a manufacturer of heat exchangers and fans, has expanded its use of Flomerics' EFD.Pro from strictly research and development to everyday engineering design.

EFD.Pro is used by design engineers interested in understanding flow and heat transfer in their products.

To facilitate a successful transfer of "CFD know-how" from one department to the next, the Bronswerk engineering team has recruited two college students.

Bas Bovenkamp and Willert Boevee, who will be graduating with mechanical engineering degrees in June from the prominent Windesheim School of Engineering and Design in the Netherlands, are working on this project as a part of their undergraduate coursework.

Bronswerk is a designer and manufacturer of heat exchangers (shell and tube and air-cooled), condensers, heaters, blowers, compressors and fans.

Its products are used in the pharmaceutical, process and oil/gas industries by organisations such as Shell, Bayer, Philips and Nestle.

Bovenkamp and Boevee started to work on several examples based on flow through tubes to understand the full power of the software.

A large proportion of the heat exchanger market consists of the tube-type heat exchanger.

Tube heat exchangers are preferred for various applications due to historical performance data and the range of temperature and pressure which they can withstand.

"Tubes are deceptively simple-looking on the surface; however, flow through tube bundles can be very complex as the fluid may experience both laminar and turbulent regimes".

"When you add heat transfer to the equation then the problem becomes even more complex", Boevee said.

"We have created a fair number of visualisation plots as a result of these tests".

"They help us see what is really happening inside these tubes".

"It's a great insight when you are able to see under which conditions the flow changes or when laminar flow becomes turbulent and how quickly", added Bovenkamp.

As a by-product of this research, Boevee and Bovenkamp have created a "how-to" manual for the engineering team.

This manual offers step by step instructions on how to use EFD.Pro for specific projects.

"As EFD.Pro is a general purpose CFD tool, it has a lot of functionalities".

"Our range of applications is quite well defined so we wanted to create a handbook that would guide our engineers without having to get up a steep learning curve every time we want to work on a project", said Van der Kamp.

"With this new Bronswerk 'how to' manual, all our designers will be able to use EFD.Pro to its full potential for everyday engineering".
