1. 16. Numerical and experimental studies of blast loading

   Författare :Björn Zakrisson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : In the past decade, there has been an increasing demand from governments for high level protections for military vehicles against explosives. However, designing and validation of protection is a time consuming and expensive process, where previous experience plays an important role. LÄS MER

3. 17. On the mechanics of actin and intermediate filament networks and their contribution to cellular mechanics

   Författare :Björn Fallqvist; Kroon Martin; Peter McHugh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; actin; cell; mechanical; constitutive; intermediate; continuum; constitutive; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : The mechanical behaviour of cells is essential in ensuring continued physiological function, and deficiencies therein can result in a variety of diseases. Also, altered mechanical response of cells can in certain cases be an indicator of a diseased state, and even actively promoting progression of pathology. LÄS MER

4. 18. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction

   Författare :Kadir Burak Korkmaz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical friction line; form factor; CFD; measurement uncertainty; power prediction; EFD; verification and validation; Combined CFD EFD Methods;

   Sammanfattning : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

5. 19. Experimental Aerothermal Study on Internal Jet Engine Structures

   Författare :Isak Jonsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate Compressor Duct; Aerothermal; multi-hole probe; Turbine Rear Structure; transition; experimental; IR-thermography;

   Sammanfattning : For commercial aviation, one potential gain in efficiency can be found in the jet engine auxiliary modules, such as internal jet engine components. These components have historically largely been overlooked, prioritising units such as turbines or compressors. LÄS MER

7. 20. Noise radiation from drill steels : and other experimental investigations in acoustics and fluid mechanics

   Författare :Jan-Erik Ögren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Drill rod noise has become a major noise source in percussive drilling. Generation of flexural waves, which seem to be responsible for most of the noise, is studied in a model with dynamic photoelasticity and in the real drill rod with strain gauge technique. LÄS MER
