1. Computation of Thermal Development in Injection Mould Filling, based on the Distance Model
Sammanfattning : The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion ([Aronsson], 1996).The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.

2. Development of Numerical Methods for Turbulent Flow in Complex Rotating Systems
Sammanfattning : A computer code has been developed to predict three-dimensional incompressible turbulent flow in complex rotating geometries. The application in mind is turbomachinery in general. However such a code is able to treat a large number of problems in fluid mechanics. LÄS MER
3. Towards 3D modelling of Compression Moulding of SMC
Sammanfattning : The automotive industry is facing ever increasing demands for reduced emissions, and lightweight solutions are thusly required. One field that has significant potential in this regard is composite materials, which can offer a good combination of weight reduction and mechanical properties. LÄS MER
4. VLF and ULF Waves Associated with Magnetospheric Substorms
Sammanfattning : A magnetospheric substorm is manifested in a variety of phenomena observed both in space and on the ground. Two electromagnetic signatures are the Substorm Chorus Event (SCE) and Pi2 pulsations. The SCE is a Very Low Frequency (VLF) radio phenomenon observed on the ground after the onset of the substorm expansion phase. LÄS MER
5. Testing and analysis of composites with 3D woven reinforcement
Sammanfattning : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. LÄS MER
