2. 1. Numerical analysis of coalescence-induced jumping droplets on superhydrophobic surfaces

   Author : Konstantinos Konstantinidis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; jumping droplets; immersed boundary; CFD; surfaces; superhydrophobic; contact angle; VOF; coalescence; self-cleaning; wetting; hysteresis;

   Abstract : Bio-inspired superhydrophobic surfaces are used in numerous technological applications due to their self-cleaning ability. One of the several mechanisms reported in literature and responsible for self-cleaning is the phenomenon of coalescence-induced jumping of droplets from such surfaces. READ MORE

4. 2. Mechanical Analysis of Lubrication and Lubricants

   Author : Jonas Ståhl; Maskinelement; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; Maskinteknik; hydraulik; akustik; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering;

   Abstract : This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. READ MORE

5. 3. Numerical Modeling of Atomization in Spray Systems

   Author : Michele Pütz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spray modeling; quadrature-based moment methods; atomization; numerical simulation; Multiphase; population balance equations;

   Abstract : Dispersed multiphase flows refer to dynamic systems comprising two or more phases where at least one phase is in the form of fine particles evolving in and interacting with a surrounding fluid. Spray systems fall into that category. READ MORE

6. 4. Topics in color measurement

   Author : Lars Mattias Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Color characterizations of printing situations are essential for a correct color reproduction. To obtain a good color characterization, knowledge about the substrate, the printing process and the printer function are all of great importance. READ MORE

7. 5. Large eddy simulation using linear eddy sub-grid mixing modeling

   Author : Salman Arshad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear Eddy Model; Large Eddy Simulation; LES-LEM; Splicing;

   Abstract : As emissions regulations are getting stricter and efficiency requirements of engines are increasing, different concepts to improve combustion are beinginvestigated. For example lean stratified premixed combustion, homogeneous charge compression ignition(HCCI), use of more exhaust gas recirculation (EGR) to reduce NOx etc. READ MORE
