<2006: Strategy=StimulationFluid and Solid Mechanics (FSM)
• Concerns: foundation of FSM within IMPACT
• Core field: multiphase flows with internationally renowned research groups (prices, editors journals, CoE, ...)
• Multiphase flows:- e.g. flows with air bubbles/water, fluid/particles, bubbles/particles/fluid
- in industry and nature.
25 september 2009 Review 2003 - 2008, Basics/FSM 3
Transition projects 2003-2004
• Bubbles in microfluidics (PoF/FCRE) • Flow of granular matter in thin layers and open
channels:- flow of dry particulates down inclined chute
- relevance: solve bottlenecks with particulate flows in industrial processes
- Bokhove (NACM) & Van Sint Annaland & Kuipers (FCRE).
> 2 research groups! (p23). E.g.:
25 september 2009 Review 2003 - 2008, Basics/FSM 4
Transition project: flow of granular matter in thin layers and open channels, e.g.
• Int. projects Geophys. Fluid Dyn. program 2005 & 2007 U.S.A.• articles international journals; chapter encyclopedia• STW grant submission, with Corus, BASF, Unilever• postdoc/UD (MSM/NACM) Center of Excellence FSM.
Results & spin-off:

Synergy projects 2005-2006
• Always involves more than 2 research groups! (p23).
• E.g. (p23):- Van der Hoef (FCRE) & Bokhove (NACM)- project on slurry (solid particles/water) flows:
25 september 2009 Review 2003 - 2008, Basics/FSM 6
Slurry flows
- laboratory experiments- mathematical modeling &
analysis- CFD nonlinear flow
- delivery of tools
- ... application: chemical bed reactors with 3-fase flows.

Managed projects 2006-2007
• We, as IMPACT team, took part in set-up of Multi-Scale Mechanics (MSM-CoE) program within national Smartmix funding opportunity:
- extensive contacts with 3TU & industry ...
- but, Smartmix program abolished: Smartnix (nix=nothing)
- yet direct spin-off: current STW program on MSM.

Managed projects ...
• Necessary “glue”:
- organized workshops as part of UT-IMPACT spearhead program “dispersed multiphase flows”
- Study Group Mathematics with Industry 2008
- grand IMPACT colloquia, e.g.:
25 september 2009 Review 2003 - 2008, Basics/FSM 9
Strategic Innovation Programs (SIPs)
• larger thematic & focused projects (... 3 pdocs, ... 6 groups)
• still curiosity driven, risky, fundamental and academic
• but contacted relevant industries in advance
• “user committee” to fast track transition fundamental to industrially relevant fundamental research & external funding.
25 september 2009 Review 2003 - 2008, Basics/FSM 10
... SIP1 ...• Computational multi-scale modelling of super-dispersed
multiphase flows- ‘super-dispersed’: no longer possible to simulate particle
trajectories individually; too many- criterion: amplify our strengths ...
• Heterogeneous Multi-scale Modelling:
25 september 2009 Review 2003 - 2008, Basics/FSM 11
• Rare view into iron-ore melting furnace with inflow pellets during inspection cycle
• Rotating, inclined chute as filling channel or iron-ore pellets, sinter and coke
• Photo courtesy: Corus. ... SIP1 ...
25 september 2009 Review 2003 - 2008, Basics/FSM 12
Outlook 2009-2010: SIP2
• Fundamentals of multiphase flowsthrough deformable solids
- geotechnical applications: fraccing, enhanced
oil recovery, & C02-sequestration
- people of 6 groups, 3 intertwined projects
- in discussion with industrial partner (+).
25 september 2009 Review 2003 - 2008, Basics/FSM 13
• ... SIP2 ... 3-4 intertwined projects: - experiment on shape & flow fluid-cracked gelatine - molecular dynamics: determine stress around crack front - same for transparent realistic gelatine-glass particle “rock” - ... alterations & variations via input industrial partner
• Oil, food & health industry (intrusion in soft matter), ....
Intrusion green fluid (“oil”) into gelatin (“rock”), previous crack=red.

Conclusion• “IMPACT stands for reallynew cutting-edge research,of international standing;through excellent contactsits research is directlyaccessible to industry ...and society ...
• ... IMPACT stands for synergetic research ...
• ... IMPACT works.”
