1. 6. Interior Flow and Formation of Plain Orifice Sprays

   Författare :Zachary Falgout; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ballistic Imaging; Sprays; Fluid Mechanics; Mixture Formation;

   Sammanfattning : This thesis will summarize recent experimental observations of spray formation in highly atomizing plainorifce sprays, the kind commonly produced by fuel injectors in compression ignition internal combustionengines. Two special interactions will be addressed in detail: primary atomization under elevated ambientpressures and temperatures and orifce ow effects on primary atomization. LÄS MER

3. 7. Active cellular forces in variable mechanical microenvironments

   Författare :Adele Khavari; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traction force; Gradient substrate; Alginate 3D culture; Durotaxis; mechanics;

   Sammanfattning : Our bodies are immensely complex structures, with various systems, organs, and processes that are not only biochemically driven, but strongly dependent on physical mechanics.  At the heart of all these processes are cells, which must generate forces to adhere, spread, differentiate, grow, and move.

4. 8. Modeling of dielectrophoresis in micro and nano systems

   Författare :Yuan Lin; Gustav Amberg; Hywel Morgan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dielectrophoresis; micro particle; molecular dynamics; single-walled carbon nanotubes; hydrodynamics; particle-particle interaction; superimposed; multi-step; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : This thesis presents models and simulations of dielectrophoretic separation of micro and nano particles. The fluid dynamics involved and the dielectric properties of water inside single-walled carbon nanotube are studied as well. LÄS MER

5. 9. Numerical modeling of dielectrophoresis

   Författare :Yuan Lin; Gustav Amberg; Olof Runborg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectrophoresis; orientation of rotation; fluid particle dynamics; microparticle; molecular dynamics; hydrodynamics; particle-particle interaction; superimposed; mobility; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : We investigate the dielectrophoretic separation of microparticles. Two different models are formulated in two characteristic time scales. The first model mainly accounts for the orientation behavior and rotational motion of non-spheric microparticles. The concept of effective charge is suggested to calculate the finite size non-spheric particles. LÄS MER

7. 10. On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines

   Författare :Henrik Bladh; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Incandescence; Laser Diagnostics; LII; Soot; Model; Engine; Particulates; Soot volume fraction; Combustion; Physics; Fysik; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; relativity; kvantmekanik; klassisk mekanik; termodynamik; statistisk fysik; relativitet; Gases; Gaser; fluid dynamics; plasmas; Teknik; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; fluiddynamik; plasma; Technological sciences; Laser technology;

   Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER
