2. 1. A Novel Immersed-Boundary Method for Multiple Moving and Interacting Bodies

   Author : Andreas Mark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; DNS; immersed-boundary method;

   Abstract : This thesis describes the development, implementation and validation of an implicit, second order accurate, finite-volume and instationary immersed-boundary method for simulating the detailed flow around multiple arbitrary moving and interacting bodies. The potential for flows including moving bodies or boundaries, such as multiphase flows still has to be fully realized. READ MORE

4. 2. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies

   Author : Andreas Mark; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; DNS; Fluid-structure interaction; Mirroring immersed boundary method;

   Abstract : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. READ MORE

5. 3. Numerical Simulations of the Urban Microclimate

   Author : Patricia Vanky; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; Immersed Boundary; Experimental validation; Wind comfort; Urban microclimate;

   Abstract : As global urbanization is accelerating and the majority of the world's population continues to reside in cities, sustainable urban development is becoming increasingly crucial. Evaluation of the urban microclimate is a vital aspect of planning sustainable cities, as it can significantly impact on the health and comfort of urban residents. READ MORE

6. 4. 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

7. 5. Detailed simulations of droplet evaporation

   Author : Giandomenico Lupo; Christophe Duwig; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

   Abstract : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.
