Traffic Networks and Flows over Time [PDF]
In view of the steadily growing car traffic and the limited capacity of our street networks, we are facing a situation where methods for better traffic management are becoming more and more important. Studies show that an individual „blind“ choice of routes leads to travel times that are between 6 % and 19 % longer than necessary.

A Stackelberg strategy for routing flow over time [PDF]
Routing games are used to to understand the impact of individual users' decisions on network efficiency. Most prior work on routing games uses a simplified model of network flow where all flow exists simultaneously, and users care about either their maximum delay or their total delay.

Effect of Surface Morphological Changes on Flow Over a Sphere [PDF]
An experimental investigation was undertaken to examine the effect of a morphing surface on the flow over a sphere in the Reynolds number range of 5x10⁴ to 5x10⁵. Here, a morphing surface is defined as a continuous surface that undergoes small amplitude

Experimental study of time-averaged flow and turbulence over asymmetric tidal dunes [PDF]
Asymmetric tidal dunes with intermediate (10–17°) to low-angle slopes (< 10°), usually with an irregularly-shaped lee side, are often found in natural, constrained tidal environments such as tidal rivers, estuaries and tidal channels.

Change in drag, apparent slip and optimum air layer thickness for laminar flow over an idealised superhydrophobic surface [PDF]
Analytic results are derived for the apparent slip length, the change in drag and the optimum air layer thickness of laminar channel and pipe flow over an idealised superhydrophobic surface, i.e. a gas layer of constant thickness retained on a wall.

Time varying flow over mountains: temperature perturbations at the surface
It is shown that the linearized potential temperature perturbation equation at the surface can be solved analytically for time dependent mean flow over a two dimensional mountain. This solution is discussed briefly for the situation without damping where

Have trends changed over time? A study of UK peak flow data and sensitivity to observation period [PDF]
Classical statistical methods for flood frequency estimation assume stationarity in the gauged data. However, recent focus on climate change and, within UK hydrology, severe floods in 2009 and 2015 has raised the profile of statistical analyses that ...

Micropolar fluid is one type of non-Newtonian fluid which consists of non-deformable spherical particles that suspended in viscous medium. In this paper, the problem of two-dimensional boundary layer flow over a permeable shrinking sheet with time ...
