Research areas on Fluid Mechanics
Fluid Mechanics research is conducted using modern methods in a creative environment and often in large groups with researchers from other disciplines and/or universities/companies.
Non-stationary flow
Common for the projects is that the scale is relatively large and it is therefore of interest to study the effect of the scale on overall flow fields and the modelling of them. Main areas of applications are hydropower and mining industries. A general methodology is to first focus on details and then the flow through larger systems of components as well as the interaction with solid components.
Porous media flow
Flow through porous media is of importance in many natural and industrial processes. This is reflected by a rather large number of projects within this area dealing with mechanical and chemical filtration, drying, deformation of the porous media and high Reynolds number flow. Examples of areas of application are composites manufacturing internal erosion in embankment dams, reactive filters, iron ore pellets and dewatering of paper.
Multiphase flow
Most industrial processes have elements of multiphase flows. In our case we deal with suspensions of different concentrations (dilute, semi-dilute and concentrated) flowing at different Reynolds number. We also model combustion. Examples of areas of application are transport of nanofibres in the human lung, reduction of NOx in combustion processes, spray processes in steel and mining industry and composites manufacturing.
Free surface flow
A special branch of multiphase flow is free surface flow with application to, for instance, flow in rivers, flow in open channels and wetting flow during composites manufacturing. Of general interest is to understand how to model such flows. Currently three methods are considered, solid surface with free slip, Volume of fluids and Smoothed particle hydrodynamics.
