21. Turbulence-droplet interaction modelled by One-Dimensional-Turbulence
Sammanfattning : A stochastic model to study droplet/particle influence on the gas phase using the One-Dimensional-Turbulence model (ODT) is evaluated. To address one of the major problems for multiphase flow simulations, namely computational costs, the dimension-reduced model is used with the goal of predicting certain classes of these flows more efficiently.

22. Analytical and Numerical Studies of Internal Swirling Flows
Sammanfattning : Swirling flows are common in technical applications, e.g. turbines, pumps, fans, compressors and combustors. LÄS MER
23. Models, methods and tools for car body development
Sammanfattning : The research presented in this licentiate thesis has been carried out at the advanced body engineering group at Volvo Car Corporation (VCC). The research has been done while enrolled at the Division of Computer Aided Design (CAD) at Luleå University of Technology. LÄS MER
24. Simulation driven product development applied to car body design
Sammanfattning : This thesis deals with the development of complex mechanical structures, from concept to detail design, as applied to car bodies. Efforts have been made to clarify how computer tools and analysis methods are used in product development in industry today. LÄS MER
25. Non-linear mechanics of nanocellulose foams
Sammanfattning : There has been a growing interest in nano-fibrillar cellulose (NFC), which has been fuelled not merely by the advantages it presents in terms of strength to weight ratio and biodegradability, but also owing to the recent advances in production techniques. NFC foam is essentially a hierarchical structure, wherein nanofibrils account for the smallest scale, with the pores/cell walls forming the meso scale. LÄS MER
