About Demcon

Each one of our companies differentiates itself in its own domain with unique expertise and skills. This way they help customers improve their performance and achieve more. On the basis of their passion for technology our companies are able to combine forces. By sharing knowledge and working together we increase our social impact.

Demcon multiphysics is a mechanical and process technology specialist in heat transfer, fluid dynamics and structural analysis. 

What are you going to do?

We are increasingly being asked by the market whether and how aero-acoustic simulations can be used in the low-noise development of products. Too often it is found afterwards that the noise requirements are not met and then adjustments are difficult and expensive. It is therefore desirable to detect and solve noise problems at an early stage. The question is therefore: can aeroacoustic simulations be used effectively for this purpose?

For this assignment we are working together with Brink Climate Systems, experts in ventilation solutions in the civil market. They develop various ventilation systems and test these products against sound requirements in their reverberation chamber. Brink is interested in the possibilities of aero-acoustic simulations during the development process.

For this thesis the first step will be to find out which different aeroacoustic simulation techniques are available to calculate sound based on a flow field. These techniques should be validated in a CFD package on the basis of simple flow fields, whose sound radiation is known. This is, for example, the flow in a curve or around an obstruction in a channel.

Once we have mastered the understanding of these simulation techniques, they can also be applied to the flow generated by a fan in a ventilation system of Brink Climate Systems. Here we will limit ourselves to the duct noise; we will leave out the cabinet radiation. In this way, you will answer the question of whether aero-acoustic simulations can be effectively applied for the early detection of noise problems of this type of ventilation system.

What do you bring to the table?

We are looking for a talented student(s) studying mechanical engineering, physics or similar with a specialization in fluid dynamics or acoustics. You are driven, eager to learn and easy to communicate with. Also, you are not afraid to tackle difficult problems and you have affinity with numerical simulations. A high degree of independence is expected.

What do we offer you?

Demcon offers a dynamic, growing and innovative organization. With our complex projects and multidisciplinary teams, we offer a good climate for this graduation project. Thanks to enthusiastic and dedicated colleagues, our working atmosphere is good, open and informal. You will be supervised (daily) by a colleague from our department and someone from Brink Climate Systems. We welcome your own initiative and give you room to express this. Furthermore, we offer you a graduation allowance and a lot of flexibility.
