WO Graduation Assignment: CFD study of turbocharger and water pump in Eindhoven

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.

We are looking for an independent trainee with a solid background in fluid dynamics and heat transfer and with experience in CFD simulations. Knowledge on (diesel) engine is appreciated.​ Required is a master in applied physics, mechanical engineering, automotive engineering or aerospace engineering Fluent English is mandatory. Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments. Due to current COVID-19 pandemics this internship might be done partially remotely and partially at DAF Eindhoven.

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.
