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 ... En savoir plus
Introduction The echolocation signals of dolphins consist of forward-projected sound pulses that reflect off objects and are used to probe underwater surroundings. Despite rigorous studies of dolphin echolocation, there remain questions about how echolocation sounds are produced and ... En savoir plus
Polydimethylsiloxane (PDMS) is a biocompatible material widely used in biomedical applications such as implantable sensors. A realistic modeling of PDMS in acoustic-mechanic simulation is useful especially for medical applications which use ultrasonic waves as interrogation source. ... En savoir plus
Simulations usually depend on a variety of parameters like geometric dimensions, process parameters, loads, or material properties. Typically, some of these parameters are fixed whereas others may be varied to obtain a special result. In many cases a simple sweep can be used to examine ... En savoir plus
The design of products in the audio industry is to a large extent done via a combination of prior knowledge and trial-and-error. Such an approach will sometimes be seen described as an ‘optimization’ of said products, but we will here focus on the formal mathematical approach of ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
When dealing with space and aerospace equipment, their ability to withstand the strong excitations produced during the launch must be tested by the manufacturers according to international standards requirements. In fact, structural subsystems of the rockets are commonly released by ... En savoir plus
There are different possibilities to simulate a bolted joint. If only the connection of parts in an assembly with the stress distribution and surface pressure between the components without the bolt itself is of interest, the thread of the bolt is omitted and only the effect of bolted ...

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 ... En savoir plus
