+ Short Introduction
+ Engineering Mechanics (ED & SOCM)
(Hans Goossen)
+ Fluid Mechanics (FM)
(Gerrit Elsinga)
+ Praktijk: a study in SFM &
an internship at Shell
(Gilles de Combe)
+ Some more stories
+ Questions?Why study ‘Solid and Fluid Mechanics’?
- Some examples:
- Rattleback
- Fingering ‘Saffman-Taylor instability’
- Elastic Fluid
2Why study ‘Solid and Fluid Mechanics’?
- How much? (in my design)
(deformation, strength, resonance frequencies)
-> ME-PME (Precision and Microsystems Engineering)
- How much? (in my design)
(chemical conversion, power production)
-> ME-SPET (Sustainable Process & Energy Technology)
- Why and how? (we still could use it in a design)
(‘what is the underlying physics’)
-> ME-SFM (Solid and Fluid Mechanics

SFM is about the fundamentals of Mech. Eng.
Interdepartmental between P&E and PMEExample pipe friction: Moody-chart? (1)
• We want to understand turbulent friction (flow structures)Example pipe friction: Moody-chart? (2)
• Movie of Direct Numerical Simulation of ‘realistic’ turbulence

Internship can be done abroad:
Recent in California-Davis, ETH (Zürich), Osaka, NTNU,
DLR (Göttingen), Numeca (Brussels)…
But more local is possible as well;
Recent in TUDelft, Teijin, KNMI, Shell, Heerema…
But the best story is a real-life experience:
Gilles de Combe
18Internship (2)
Teijin (production of Aramid-fibers)
19Master-thesis project 45 EC
Can be done in a company, usually in ‘your laboratory’.
Prediction of turbulent transition through ‘trip wires’ using flow simulation.
Prediction of CT-scanner floor stability

32(slightly) different interests?
SOLID MECHANICS
- You probably already joined the presentation of
Precision and Microsystems Engineering (PME)
(or contact ir. Jan Neve, PME-coordinator)
FLUID MECHANICS
- Join the presentation on Thursday of
Sustainable Processes and Energy Technology (SPET)

33Honours Programme Master (HPM)
• A tailor-made rigorous programme of 30 EC for motivated students seeking a
unique challenge in their course work.
• Build your own programme based on an inter- or mono-disciplinary
approach.
• Become part of an active honours community and benefit from social and
networking events.
How does it work?
• Information session
• Selection process
• Match-up with coach
• Planning the programme
nd
• Start 2 semester of master
• Certificate upon successful completion
