1. Integrated design systems supporting thermal-structural analysis in product development
Sammanfattning : This work covers integrated computer-aided applications for design and analysis in particular different integrated design systems for thermal and structural simulations. Two different design systems have been integrated to improve efficiency in product development, i.e. reduced lead-time and higher quality of the product. LÄS MER
2. Characterization of cellulose pulps and the influence of their properties on the process and production of viscose and cellulose ethers
Sammanfattning : Today’s market offers an ever-increasing range of cellulose pulps (derivative pulps) made fromvarious wood types through different delignification processes. Each pulp segment has its uniquecharacteristics, which makes it difficult for the producer of cellulose derivatives to choose the mostsuitable pulp for optimum processability and product quality.

3. Weak Boundary and Interface Procedures for Wave and Flow Problems
Sammanfattning : In this thesis, we have analyzed the accuracy and stability aspects of weak boundary and interface conditions (WBCs) for high order finite difference methods on Summations-By-Parts (SBP) form. The numerical technique has been applied to wave propagation and flow problems. LÄS MER
4. High order summation-by-parts methods in time and space
Sammanfattning : This thesis develops the methodology for solving initial boundary value problems with the use of summation-by-parts discretizations. The combination of high orders of accuracy and a systematic approach to construct provably stable boundary and interface procedures makes this methodology especially suitable for scientific computations with high demands on efficiency and robustness.

5. Application of Parallel Computers to Enhance the Flow Modelling Capability in Aircraft Design
Sammanfattning : The development process for new aircraft configurations needs to be more efficient in terms of performance, cost and time to market. The potential to influence these factors is highest in early design phases. Thus, high confidence must be established in the product earlier than today. LÄS MER
