2. 1. Design of Powder Core Motors

   Author : Avo Reinap; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; claw-pole motor; Soft magnetic composite; Electrical engineering; 3D finite element analysis; Elektroteknik;

   Abstract : The goal of the study presented in this thesis is to evaluate the advantages and drawbacks of using powder technology in the design of the iron core of small claw-pole electric motors. The use of soft magnetic composites (SMC) and compaction technology allows the creation of complex 3D iron cores. READ MORE

4. 2. Modeling and Simulation of Contacting Flexible Bodies in Multibody Systems

   Author : Iakov Nakhimovski; Dag Fritzson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mechanic; simulation programme; algorithms; computer software; industrial application; Computer science; Datavetenskap;

   Abstract : This thesis summarizes the equations, algorithms and design decisions necessary for dynamic simulation of flexible bodies with moving contacts. The assumed general shape function approach is also presented. The approach is expected to be computationally less expensive than FEM approaches and easier to use than other reduction techniques.

5. 3. On the ECO2 multifunctional design paradigm and tools for acoustic tailoring

   Author : Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Per Wennhage; Franck Sgard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle design; planned obsolescence; anisotropy; porous materials; sound absorbing materials; acoustic modelling; power balance; energy assessment; dissipated power.; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : Nowadays vehicle design paradigm influences not only the effectiveness of the different means of transport, but also the environment and economy in a critical way. The assessment of the consequences that design choices have on society at large are necessary to understand the limits of the methods and techniques currently employed. READ MORE

6. 4. CFD as a tool for analysis of complex geometry : Perspectives on time efficient simulations of interior household appliance components

   Author : Kamal Rezk; Ola Holby; Lars Davidson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Tumble dryer; Fluid mechanics; Design process; Heat exchanger; Comsol MultiPhysics; Volume averaged method; Fluid mechanics; Strömningsmekanik; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : Throughout recent years, computer based programs has been applied to solve and analyze industrial problems. One of these developed programs is the Computational Fluid Dynamics (CFD) program. The purpose of implementing CFD analysis is to solve complex flow behavior which is not possible with ordinary calculus. READ MORE

7. 5. Methods for Reducing the Complexity of Geometrical Structures Based on CFD Programming : Time Efficient Simulations Based on Volume Forces Coupled with Single and Two-phase Flow
