  1. Basics -Fluid and Solid Mechanics- Coordinator Onno Bokhove July 2006 to 2008 Review 2003 - 2008, Basics/FSM

  2. <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. 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.: Review 2003 - 2008, Basics/FSM

  4. Transition project: flow of granular matter in thin layers and open channels, e.g. Results & spin-off: • 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. Review 2003 - 2008, Basics/FSM

  5. 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: 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. Review 2003 - 2008, Basics/FSM

  7. 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. Review 2003 - 2008, Basics/FSM

  8. 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.: 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. 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: 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 ... Review 2003 - 2008, Basics/FSM

  12. Outlook 2009-2010: SIP2 • Fundamentals of multiphase flows through deformable solids- geotechnical applications: fraccing, enhanced oil recovery, & C02-sequestration- people of 6 groups, 3 intertwined projects- in discussion with industrial partner (+). 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. Review 2003 - 2008, Basics/FSM

  14. 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.” Review 2003 - 2008, Basics/FSM
