21. A study of hydroelastic fluid-structure interaction with application to immersed cantilevers
Sammanfattning : This study presents an approach for partitioned fluid-structure interaction (FSI) applied to large structural deformations, where an incompressible turbulent solver is combined with a structural solver. The implementation is based upon two different open-source libraries by using MPI as a parallel communication protocol, the packages deal. LÄS MER
22. Thermodynamics and Kinetics in Metallurgical Processes - with a Special Focus on Bubble Dynamics
Sammanfattning : Gas stirring is commonly used in the steelmaking processes to reinforce chemical reactions, kinetic transfer, and inclusion removal, etc. This dissertation concentrates on multiphase flows with gas bubbling to study fluid dynamics and thermodynamics in metallurgical processes.

23. Some PDAE aspects of the numerical simulation of a CO2 heat pump
Sammanfattning : We consider network modelling and numerical simulation of a simple CO2 heat pump consisting of a compressor, a valve and two heat exchangers. In a first step we investigate analytical and numerical properties of the heat exchanger model. LÄS MER
24. A Study of Bubble and Inclusion Behaviors in a Liquid Steel Bath
Sammanfattning : The bubble formation processes in a water model experiment were measured by a high-speed camera. Nozzle diameters of 0.5 mm, 1 mm and 2 mm were investigated under both wetting and non-wetting conditions. LÄS MER
25. Convergence and stability analysis of stochastic optimization algorithms
Sammanfattning : This thesis is concerned with stochastic optimization methods. The pioneering work in the field is the article “A stochastic approximation algorithm” by Robbins and Monro [1], in which they proposed the stochastic gradient descent; a stochastic version of the classical gradient descent algorithm.
