Complete Design of a High Power Ultrasonic Flow-Cell Reactor with Special Air Cooling System

Lorenzo Spicci1
1Everywave Srl

Ultrasonic flow-cell reactors are used for many industrial applications, where fluid substrate is sonicated in a small region, where very high ultrasonic acoustic power is present. The electromechanical transducer (converter) that drive the sonotrode inside the flow-cell is designed in ... Per saperne di più

Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes

Dr. Vladimir Burlaka1, Thorsten Fröba1
1X-RAY WorX GmbH, Siemensstraße 26, 30827 Garbsen, Germany

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... Per saperne di più

Benefit of Vapor Consideration for LPBF Additive Manufacturing Process Simulation

1Laboratoire PIMM, Arts et Metiers Institute of Technology, CNRS, Cnam, HESAM Universite
2I2M, Arts et Metiers Institute of Technology, University of Bordeaux, CNRS, Bordeaux INP, INRAE

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Per saperne di più

An Analysis of the Synchronous Transport Phenomena Involved in Pasta Drying Process

G. Adduci1, E. Manoli2, E. Cardaropoli2, G. Coppola1, F. Petrosino1, S. Curcio1
1DIMES, Università della Calabria, Cosenza, Italy
2Barilla G. e R. Fratelli, Parma, Italy

This work is focused on the development of a physical-mathematical model capable of predicting the temperature and water content fields within a pasta sample which is exposed to a stream of drying air flowing under turbulent conditions.
