   Abstract : The work presented in this thesis includes two stages in a research project at the Rolls-Royce University Technology Center (UTC) at Chalmers Technology University. The objective of the project is to develop an optimization technique for ship/propeller interaction. READ MORE

6. 9. JOINING SEQUENCE OPTIMIZATION IN COMPLIANT VARIATION SIMULATION

   Author : Roham Sadeghi Tabar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compliant Variation Simulation; Sequencing; Optimization; Joining;

   Abstract : Disturbances in the manufacturing and assembly processes cause deviation and geometrical variation from the ideal geometry. This variation eventually results in functional and aesthetic problems in the final product. Being able to control the disturbances is the desire of the manufacturing industry. READ MORE

7. 10. Development of shape optimization for internal flows

   Author : EYSTEINN HELGASON; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal flow; computational fluid dynamics; sensitivities; continuous adjoint method.; optimization;

   Abstract : This thesis describes the development of an adjoint based optimizationmethod.The goal is to develop a robust method capable of handling multipledesign variables, whereastraditional methods have shown to be too costly for many design parameters.The main application is for internal flow geometries within theautomotive industry.
