We use ODTLES, a multi-dimensional extension of the One-Dimensional-Turbulence model (ODT). ODT describes turbulent advection on a 1D sub-domain using a stochastic process for turbulent advection. These 1D sub-domains are coupled to obtain a 3D approach. ODTLES is applied to channel flow. Preliminary results for the pdf of the wall shear stress...

In this paper we analyse the impact of property ownership on the saving behaviour of households. We are particularly interested in investigating whether homeowners save more than renters or not. A related question is whether mortgage payments and other regular savings are substitutes or complements for German households. To answer these...

We present hybrid capturing/tracking methods for the simulation of turbulent premixed flames in meso- and large-scale geometries. Such schemes resemble a tracking schemes in that the flame front is explicitly computed and propagated using a level set method. The flame-flow-coupling uses in-cell-reconstruction. In cut cells, burnt and unburned...

Experimental analysis of the diffusiophoretic effect in turbulence demonstrates that preferential concentration of particles driven by the combined action of turbulence and inhomogeneous distribution of salinity exists. Additionally, theoretical predictions on the particle behavior could be confirmed. We provide evidence that inhomogeneous salt...

The paper reports on the application of scientific CMOS cameras and high power LED light sources for three-dimensional particle tracking in large enclosures. An open source software is adapted to work with 16 bit grey value images. As fixed thresholds pointed out to be inappropiate for particle detection in 16 bit images due to temporal and...

The use of dynamic bonds in self-healing polymeric systems allows restoring of the chemical structure and mechanical properties multiple times. In this respect, the use of ionomers represents a promising approach. The strong interaction between ionic moieties within a non-polar matrix leads to microphase separation and a behavior similar to...

One-dimensional turbulence (ODT) is a stochastic simulation in which 3D turbulence effects are captured on a notional 1D line of sight by introducing instantaneous spatial re-arrangements (maps) that represent advection by notional turbulent eddies. These eddy events incorporate the possibility of kinetic-energy changes that are equal and...

The present paper focuses on a numerical approach based on the Riemann problem to simulate liquid flows with phase changes. Thereby, the flow properties include velocities from O(1) m/s to O(100) m/s and pressures from p approx 0 bar to O(1000) bar. The thermal and caloric behavior of liquid and vapor will be described by suitable equations of...
