Permeability of three-dimensional random fiber webs
1998
We report the results of essentially ab initio simulations of creeping flow through large threedimensional random fiber webs that closely resemble fibrous sheets such as paper and nonwoven fabrics. The computational scheme used in this Letter is that of the lattice-Boltzmann method and contains no free parameters concerning the properties of the porous medium or the dynamics of the flow. The computed permeability of the web is found to be in good agreement with experimental data, and confirms that permeability depends exponentially on porosity over a large range of porosity.

DD ″Creeping eruption″
2015
Unter dem Begriff ″creeping eruption″ werden verschiedene Infektionen oder Infestationen gefuhrt. Hierunter fallen zum Beispiel wandernde subkutane Schwellungen mit Rotung und Urtikaria bei Gnathostomiasis, kutaner Paragonimiasis (Lungenegelinfektion) oder Fasziolose (Leberegelinfektion). Ahnliche wandernde Symptome sind auch bei Befall mit Fliegenmaden (″migratory myiasis″) moglich. Nicht alle derart bezeichneten Erkrankungen haben einen unmittelbaren Bezug zu Hauterscheinungen.
CFD simulation of radially stirred baffled and unbaffled tanks
2019
Stirred tanks typically employed in process industries are provided with baffles. Although the presence of baffles is known to guarantee good mixing rates, unbaffled vessels may be compulsory in some applications as crystallization, bioremediation, biotechnology and ore industry. A better understanding of unbaffled stirred vessels flow dynamics may allow (i) a proper design to be performed and (i) conditions/processes where baffle presence can be avoided to be recognized. In the present study, the k-ω SST was used to simulate an unbaffled tank from early to fully turbulent regime (Re≈600-33,000). The unbaffled tank simulated has a diameter T=0.19m and is stirred by a standard six-bladed Rus…
Personal correlates of problematic types of social media and mobile phone use in emerging adults
2019
We investigated the occurrence of selected types of problematic social media and mobile phone use in emerging adults, specifically social media and mobile phone overuse, phubbing, creeping, and catfishing. Contemporaneous relations with age, gender, and Big Five personality traits were examined. The participants comprised 459 Slovenian emerging adults, aged 18 to 29 years (68% female). The results suggest that problematic behaviors associated with social media and mobile phone use, with the exception of catfishing, are relatively common among young people. The examined behaviors were negatively related to age, and overuse of mobile phones, social media, and creeping were more prevalent in f…
