CFD study crankcase turbulence
Master project within our Engine Development department
CFD (computational fluid dynamics) simulations are performed to improve the design of the engine (using STAR-CCM+ package) in the CAE-Engine department.
The reciprocating motion of pistons and the rotation of connecting rods and crankshaft generate turbulence and pressure waves in the gas trapped in the engine crankcase (part of the engine under the pistons and above oil level in the oil pan). Two main consequences can be expected: it might have a negative effect on engine pumping loss and it can also affect the oil jets spread underneath piston Only very limited measurements can be performed due to the location of the crankcase and the moving parts.
- The purpose of this internship is to build a CFD model of the crankcase turbulence with moving parts.
- Starting with a simple model with only reciprocated pistons. you will focus on velocity field and pressure fluctuations during an engine cycle.
- The other moving parts (first the crankshaft and then the connected rods) will be added later
- The outputs of the different models will be compared.
- You are an independent Master student in Applied Physics, Mechanical, Automotive or Aerospace Engineering;
- Background in fluid dynamics and heat transfer;
- Experience in CFD simulations;
- Knowledge on (diesel) engine;
- Your English is fluent.
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.
- 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) based on 36 hours;
- A travel allowance, if you don’t have a student travel product (provided by the Dutch government);
