+ 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?

- Some examples:

- Rattleback

- Fingering ‘Saffman-Taylor instability’- Elastic Fluid

Why study ‘Solid and Fluid Mechanics’?

3

- 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 PME

Why study ‘Solid and Fluid Mechanics’?

Example 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

on a 16000-core parallel computer

Example pipe friction: Moody-chart? (2)• We want to modify (reduce) friction: (wall; additives)

Example pipe friction: Moody-chart? (3)• Movie of fibres in pipe flow at two different concetrations

α = 20; Re = 5000 α = 60; Re = 7500

MSc Program layout

Courses (1st year)• Obligatory SFM: ~ 29 ECTS

• Obligatory specialisation: ~ 12 ECTS

• Elective: ~ 20 ECTS

• Total 60+ ECTS

• 1st semester: the fundamentals

• 2nd semester: how we use them

Projects (2nd year)• Internship 15 ECTS

• MSc project 45 ECTS

of which 10 ECTS literature study

with oral presentation.

• Possibility to combine internship and MSc project.

• For instance:

Internship in Industry

-> MSc project at University

or vice versa

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

Internship (stage) 15 EC (niet voor ex-HBO!)

Teijin (production of Aramid-fibers)

Internship (2)

Can be done in a company, usually in ‘your laboratory’.

Master-thesis project 45 EC

Prediction of turbulent transition through ‘trip wires’ using flow simulation.

Prediction of CT-scanner floor stability

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)(or contact dr.ir. Joop ter Horst, SPET-coordinator)

Or just pass by with questions...

(slightly) different interests?

Honours 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?
