16. Towards Improved Scale-Resolving Modeling and Simulations of Turbulent Flows
Abstract : Scale-resolving simulations are viewed as powerful means for predicting complex turbulentflows, as often encountered in aeronautical applications. However, since turbulent scalesspan over a considerable range from the smallest Kolmogorov scales to the largest ofequivalence to configuration size, scale-resolving computations are often demandingon computational resources and, furthermore, on the underlying numerical methodsused in the simulations.

17. Modeling and numerical simulation of hydro power flows
Abstract : This work is about high precision numerical water flow simulations of hydro power related applications, and especially draft tube flows. Because of the accuracy requirements for these types of simulations (the efficiency of a hydro power turbine can be over 90%), the work has been devided into several steps; verification, validation and modeling.

18. Multiphase continuum modeling of wood : A hybrid mixture theory approach
Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

19. Mesoscale Simulations of Atmospheric Flow in Complex Terrain
Abstract : The MIUU mesoscale model was further developed, in order to include information on large-scale atmospheric fields from global or regional atmospheric climate- and weather-prediction models. For this purpose, a new lateral boundary condition was developed and implemented into the model. READ MORE

20. Numerical modeling of air-fiber flows
Abstract : The dynamics of fiber suspensions are of great importance in applications such as the dry-forming process of pulp mats for use in hygiene products. In this forming process, fibers are transported in flowing air. The fibers interact with the fluid, and may interact with each other and interlock in flocs. READ MORE
