A digital twin is a virtual set of information replicating its physical counterpart at the utmost fidelity. Digital and physical twin benefit from bi-directional data exchange that occurs in real time and over the whole process lifecycle. Until now, experts in the design phase have ... Read More

Decarbonization of the heating sector requires the exploitation of climate-neutral energy sources and the use of natural heat storage. Shallow and deep geothermal energy can make a valuable contribution to this. The dimensioning and design of geothermal boreholes and larger borehole heat ... Read More

In recent years, the optimization of high-temperature superconductors (HTS) has shown promising potential for developing advanced cable layouts aimed at the realization of practical fusion reactors. Despite their excellent performance in terms of electromagnetic and mechanical stability, ... Read More

Preservation of biopharmaceuticals by spray freeze-drying is of great interest as it involves gentle drying and can be easily integrated with continuous manufacturing strategies. The drying of packed beds have been extensively studied experimentally, but a detailed mathematical model of ... Read More

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. Therefore, the equations concerning the transfer of ... Read More

A novel injection molding tool temperature control system based on heat pipes is being researched at the Bielefeld University of Applied Sciences and Arts (HSBI). This temperature control technology offers great potential for improving product quality and saving energy in the production ... Read More

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 ... Read More

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... Read More

The presence of oxygen in metal installations can influence their flammability, which leads to frequent combustion ignitions. Various studies have been done to characterize this ignition, in order to classify metals according to their degree of flammability, and to minimize the risk of ... Read More

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 ... Read More
