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 a moist and cold food sample. The aim of the present work is the development a fundamental multiphase approach ...

The onshore wind turbine industry must overcome many technical, commercial, and environmental difficulties. A significant element for planning consent is operational noise. Acoustic limits are strictly enforced and can lead to near-neighbour complaints as well as contractual disputes. Reactec have diagnosed, analysed and solved a problematic tonal resonance for a major wind turbine generator ...

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good understanding of the dynamics of droplets impact. In this study, the process of droplet spreading is described; ...

BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number of heterogeneous client computers connected by the Internet where each computer is assigned an individual task ...

Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl components during the setup of a real production process. This study is a preliminary contribution devoted to ...

The operation of transformers is characterised by strong dynamic interactions between the magnetic system and the electric circuits that are connected to the primary and econdary windings. Transient finite element modelling (FEM) of the transformer with coupling to SPICE circuit models containing the electrical sources and loads is a powerful means for analysis and design. This paper describes ...

Understanding the stress-strain behavior of human foot tissues and pressure map distributions at the plantar interface is of interest into biomechanical investigations. In particular, monitoring plantar pressure maps is crucial to establishing the perceived human comfort of shoe insoles. A 3D anatomical detailed FE human foot model was created, starting from CT (Computer Tomography) scans of a ...

Waterflooding is widely used in secondary oil recovery. The physics is described by the model of two-phase flow in porous media. The aim of the present work is to implement this model in COMSOL Multiphysics and to simulate the process of waterflooding. It is analyzed in two dimensions. We use layered reservoir in our study. The numerical implementation is validated, comparing with analytical ...

In a hydronic space heating system the heat output arises from natural convection and radiation from the radiators. In order to increase the heat output, without replacing the radiators with larger ones, or increasing the temperature level, the radiator can be equipped with add-onfan blowers. In the latter case, the heat output from the radiator will increase due to increased convection. This ...
