Vertical axis wind and tidal turbines are a promising technology, well suited to harness kinetic energy from highly turbulent environments such as urban areas or rivers. The power density per occupied land area of two three vertical rotors deployed in close proximity can notably exceed that their horizontal counterparts. Using acoustic Doppler velocimetry, the three-dimensional wake developed d...
Twin screw pump is a positive displacement pump, which widely used in numerous type of foodstuff applications. Numerical CFD analysis presented this paper focuses on the investigation influence clearances and non-Newtonian behaviour fluid. The operates at low rotational speed inlet pressure. As first step 3D simulation twin-screw non-rotating segment has been carried out using static mesh witho...
A new development of hybrid in-process electrical dressing of metal-bonded diamond grinding wheels is proposed in this paper. The electrical dressing method is used for overcoming the limitations of the conventional dressing methods available in relation to a super-abrasive wheel because of the hardness of its abrasive grains and the durability of its bonding material. The proposed hybrid in-pr...
A Pareto Local Search (PLS) algorithm was developed and applied to the screw configuration of co-rotating twin-screw extruders. This problem can be seen as a sequencing problem where a set of different screw elements are to be sequentially positioned along the screw in order to maximize the extruder performance. The results obtained were compared with previous results obtained with a Multi-Obje...
