Analytical and numerical validation of a plate-plate tribometer for measuring wall slip
Muhammad Hassan Asghar, Tomislav Maric, Houssem Ben Gozlen +5
We model the Darmstadt Slip Length Tribometer (DSLT), specially designed to measure viscosity and slip length simultaneously for lubrication gaps in the range of approximately 10 m…
Do Resilience Metrics of Water Distribution Systems Really Assess Resilience? A Critical Review
Michaela Leštáková, Kevin Tiernan Logan, Imke-Sophie Rehm +2
Having become vital to satisfying basic human needs, water distribution systems (WDSs) are considered critical infrastructure. They are vulnerable to critical events such as extrem…
Comparing Approaches to Distributed Control of Fluid Systems based on Multi-Agent Systems
Kevin T. Logan, J. Marius Stürmer, Tim M. Müller +1
Conventional control of fluid systems does not consider system-wide knowledge for optimising energy efficient operation. Distributed control of fluid systems combines reliable loca…
Dynamic force and torque characteristic of annular gaps -- Simulation results and evaluation of the relevance of the tilt and torque coefficients
Maximilian M. G. Kuhr, Rainer Nordmann, Peter F. Pelz
We discuss the dynamic force and torque characteristic of annular gaps resulting from an axial flow component. First, the rotordynamic influence of annular gaps with an axial flow…
Static force characteristic of annular gaps -- Experimental and simulation results
Maximilian M. G. Kuhr, Sebastian R. Lang, Peter F. Pelz
We discuss the static force characteristic of annular gaps resulting from an axial flow component. So far there is a severe lack of understanding of the flow inside the annulus. Fi…
The Activation Energy for Wall Slip
Peter F. Pelz, Tobias Corneli
The Navier slip boundary condition is interpreted as an equilibrium of shear rate and slip rate. From the argument that the slip rate shall be proportional to the molecules' collis…
Challenges in identifying simple pattern-forming mechanisms in the development of settlements using demographic data
Bartosz Prokop, Lendert Gelens, Peter F. Pelz +1
The rapid increase of population and settlement structures in the Global South during recent decades motivates the development of suitable models to describe their formation and ev…
Effects of Unsteady Heat Transfer on Behaviour of Commercial Hydro-Pneumatic Accumulators
Jakob Hartig, Benedict Depp, Manuel Rexer +1
Hydraulic accumulators play a central role as energy storage in nearly all fluid power systems. The accumulators serve as pulsation dampers or energy storage devices in hydro-pneum…
Comparison of existing aneurysm models and their path forward
John Friesen, Jonas Bergner, Mohammad Ibrahim Aftab Khan +4
The two most important aneurysm types are cerebral aneurysms (CA) and abdominal aortic aneurysms (AAA), accounting together for over 80\% of all fatal aneurysm incidences. To minim…
Efficient Powertrain Design -- A Mixed-Integer Geometric Programming Approach
Philipp Leise, Peter F. Pelz
The powertrain of battery electric vehicles can be optimized to maximize the travel distance for a given amount of stored energy in the traction battery. To achieve this, a combine…
Diffusion-driven demographics -- Turing model as a concept for the emergence of sedentism
John Friesen, Jakob Hartig, Katharina Henn +1
Sedentism was a decisive moment in the history of humankind. In a review article Kay and Kaplan quantified land use for early human settlements and found that sedentism and the eme…
An Analytical Approach for the Optimal Operation of Pumps in Booster Systems
T. F. Groß, P. F. Pöttgen, P. F. Pelz
The operation of pumps and booster systems accounts for 10% of the yearly energy consumption in Europe. Booster systems are used to ensure the water supply in multi-story buildings…
