This study focuses on comparing various fluid dynamic models for analyzing airflows within the cooking chamber of an oven. The comparison is conducted in three steps. First, a study of the fan directly connected to a test tube in suction mode, discharging radially into free space. ... En savoir plus
The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in ... En savoir plus
In the field of coding and industrial marking areas, CIJ technology is based on high speed emission of ink drops (20 m/s) which are directed onto a moving printing medium. The printing quality depends, on one hand, on drops position on the media determined by the drop charge and the ... En savoir plus
This paper presents a simulation approach to develop a model for understanding the mixing phenomenon in a stirred vessel. The mixing in the vessel is important for effective chemical reaction, heat transfer, mass transfer and phase homogeneity. In some cases, it is very difficult to ... En savoir plus
Pulsed Electric Field (PEF) technology is gaining much attention in the food industry, as it offers unique advantages in terms of food safety, preservation of the organoleptic and nutrients properties, and low energetic requirements. Winemaking processes, in particular, can greatly ... En savoir plus
Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this ... En savoir plus
Aluminum production potlines operate under significant amperage in a range of 200 kA – 600 kA. High electrical DC currents induce strong magnetic fields. MHD stability, which is a result of electrical current and magnetic field interaction within aluminum reduction cell, is one of highly ... En savoir plus
This paper presents results on the visualisation of tracks of charged particles in a non-uniform magnetic field. The field modelled is that generated by a coil driven by DC current. The motion of typical particles, such as electrons, ions and multiply-charged heavy particles has been ... En savoir plus
One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in ... En savoir plus
Toxic and hazardous air pollutants are released during chemical processes. The surrounding area of a chemical facility always has a high risk of air pollution by released chemicals. Furthermore, the personnel of the facility as well as community residents have risks of sudden ... En savoir plus
