2. 1. On the Agglomeration of Particles in Exhaust Gases

   Author : Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

   Abstract : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. READ MORE

5. 3. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer

   Author : Zhibing Yang; Auli Niemi; Fritjof Fagerlund; Tissa Illangasekare; Insa Neuweiler; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphase flow; dissolution; mass transfer; invasion percolation; immiscible displacement; fractured media; groundwater contamination; non-aqueous phase liquid; curvature; Hydrology; Hydrologi;

   Abstract : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.

6. 4. Multiphase continuum modeling of wood : A hybrid mixture theory approach

   Author : Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

7. 5. Fluid Mechanics of Solid-Liquid Suspensions – An Experimental and Numerical Study

   Author : Torbjörn Virdung; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiphase; soalescence; confined jet; computational fluid dynamics; stirred vessel; laser doppler velocimetry; particle image velocimetry; solid-liquid suspension; pitched blade; gas-liquid;

   Abstract : Multiphase flows are common in many applications in chemical, mineral, biochemical and several other process industries. Examples of equipment in which multiphase flows are encountered are stirred vessels and multiphase jets, in which suspensions are agitated by an impeller in the former case and distributed through a nozzle in the latter.
