It has been long established that Reynolds number effects can lead to flow instabilities and/or transition from laminar to turbulent flow regimes. The nature of free shear jets is well understood and heavily covered in the fluid mechanics literature. On the other hand, the study of confined nozzles presents some challenges and is still a [...]
CFD-analysis of hydrodynamic lubrication of textured surfaces
There are countless numbers of lubricated components everywhere in life and an improvement in efficiency would lead to great cost efficiency improvements in many applications. This makes it an area which is subject to a great deal of research. Here, an approach to increase the efficiency in hydrodynamic lubrication is made where the influences from [...]
CFD Simulations of Pressure Loss in Pipes with Different Geometries
The passive security systems protect the passengers when the car has an important accident. These systems are based in a good and strength car structure to not deform the passenger cabin. In Gestamp Hardtech are producing pieces with an important strength without increasing the car weight. These pieces are produced using the hot stamping process [...]
