We propose a simplified numerical method to model the flow field downstream of an axial impeller. The method can be used for any axial hydraulic machinery for which, one is less interested by the flow between the blades, than by the flow field downstream of the machinery. The method is ... 詳細を見る

Sediment transport in shallow water is of concern in many hydro-ecological problems. Erosion or sedimentation processes are not only relevant in perennial systems as rivers, lakes, reservoirs and coastal regions, but also in ephemeral phenomena like gullies, inundations and floods. ... 詳細を見る

Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. ... 詳細を見る

Computational fluid dynamics has emerged as an advanced tool for studying detailed behavior of fluid flow and heat transfer characteristics in many chemical engineering applications like packed beds. Packed beds play an important role in various chemical industries. Hence understanding ... 詳細を見る

Evaporative cooling is a promising cooling method for dissipating high heat fluxes in high power density applications. One possibility to enhance heat flux is a generation of microstructures into the cooler surface. This enlarges the cooler surface and systematically affects the fluid ... 詳細を見る

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes ... 詳細を見る

Spring-supported thrust bearings are used in huge rotor dynamic machines, generally to support the shafts from the biggest hydropower generators. Any attempt of modifying yhis type of thrust bearing implies huge investment and is associated with some risks. The goal of the present work ... 詳細を見る

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... 詳細を見る

This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... 詳細を見る

Ruptured aortic aneurysm is one of the commonest cause of mortality in developed countries. To avoid it interventional repair is an effective treatment. In the recent years the development of new therapies, such as stent implantations, allows to perform this treatment more and more ... 詳細を見る
