WO Graduation Assignment: CFD study of turbocharger and water pump

DAF Trucks is a manufacturing company. DAF products are sold and serviced throughout Europe, the Middle East, Africa, South America, Australia, New Zealand and Asia. DAF occupies a leading position in the European truck market. DAF headquarters, main plants and development center are based in Eindhoven (The Netherlands).

The department Engine Hardware & Design is responsible for the development of new engine hardware concepts and maintaining the in-production engine families. The CAE (computer aided engineering) group has an open position for a trainee.


Wat ga je doen?

CFD (computational fluid dynamics) simulations are performed to improve the design of the engine (using STAR-CCM+ package) in the CAE-Engine department. PACCAR engines are using a water pump and a turbocharger. These devices have always been difficult to model in CFD because of the rotating parts, the cavitation or the compression they can generate and the heat transfer.These components are essential for good fuel consumption and engine performance. New modelling tools are now available which makes the integration of these two components in the whole engine model possible and can result in a better design.The goal of this project is get dynamic models of the water pump and of the turbocharger. The candidate will start by reviewing the literature available on this topic. The candidate will to build and validate the CFD models against literature and test results. Several aspects will be investigated: rotating/sliding modelling, turbulence models, mesh, local compressibility effects, heat transfer, cavitation etc.

Wat krijg je er voor terug?

  • A view behind the scenes at a large international corporation;
  • You will get a lot of freedom and responsibility. We are open to your initiatives and depending on the assignment you see your results back in the workplace;
  • An experienced coach and supervisor who can teach you a lot and is willing to help you with your assignment;
  • After your graduation, you will have the opportunity to start your career at DAF;
  • An internship wage of € 450,- (WO) per month on full-time base
  • A travel allowance, if you don't have a student travel product (provided by the Dutch government);
  • A housing allowance, if you temporarily rent a room near DAF.
  • Each intern will have the opportunity to participate at the Student Event. During this event you will meet other interns and find out more about DAF/PACCAR!Would you like to know more about the experiences of other students? Here you can read stories of our former interns.

Wie is DAF Nederland

DAF is marktleider op de Nederlandse vrachtwagenmarkt. Grofweg één op de drie trucks die hier geregistreerd worden, is een DAF. Het is vooral in het lichte segment waar de Nederlandse truckfabrikant een verdere groei wil realiseren. Dicht dealernetwerk DAF beschikt in Nederland over het meest dichte en professionele dealernetwerk van alle truckmerken. Op 72 locaties is DAF vertegenwoordigd door DAF Dealers en Service Partners. In de praktijk betekent dit dat er in Nederland altijd binnen een half uur een DAF service-punt binnen bereik is.
