2. 11. Numerical simulations of industrial-scale packed-bed adsorbers

   Author : Adam Jareteg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packed Bed; Numerical Modeling; Temperature Swing Adsorption; Finite Volume Method; Industrial Scale;

   Abstract : A common technique for removing harmful substances, for either persons or equipment, from a stream is to use the phenomenon of adsorption. This technique is used in, for example, water purification, personal protection, chemical and pharmaceutical production and biomass gasification. READ MORE

4. 12. Transonic flow: large eddy simulation, numerical methods and subgrid modeling

   Author : Christian Wollblad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; SGS modeling; Transonic flow; semi-implicit numerical scheme; shock wave turbulent boundary layer interaction;

   Abstract : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. READ MORE

5. 13. IronArc a New Process for Pig Iron Production : A Numerical and Experimental Investigation Focusing on Mixing

   Author : Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixing time; Penetration depth; CFD simulations; IronArc; Water modeling; Mixing time Experiments; Omrörningstid; Penetrationsdjup; CFD simuleringar; IronArc; Vattenmodellering; Omrörningsexperiment; Metallurgical process science; Metallurgisk processvetenskap;

   Abstract : I den här studien så var syftet att undersöka omrörningen och relaterade fenomen i den nyutvecklade IronArc processen. Processen använder sig av gasinjektion genom plasmageneratorer för att smälta och reducera en slagg bestående av järnoxid. READ MORE

6. 14. Continuum modeling of paperboard for the mechanical response of converting processes

   Author : Kristofer Robertsson; Hållfasthetslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

   Abstract : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. READ MORE

7. 15. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process

   Author : Mikael Ersson; Pär Jönsson; Stein-Tore Johanssen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical modeling; top-blown converter; BOF; CFD; Thermodynamics; slag; dynamic simulations; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. READ MORE
