Calculation of the separation streamlines of barchans and transverse dunes
H. J. Herrmann, J. S. Andrade, V. Schatz +2
We use FLUENT to calculate the wind profile over barchans and transverse dunes. The form of the streamlines of flow separation at the lee side of the dunes is determined for a symm…
Multiple Invaded Consolidating Materials
A. D. Araujo, J. S. Andrade, H. J. Herrmann
We study a multiple invasion model to simulate corrosion or intrusion processes. Estimated values for the fractal dimension of the invaded region reveal that the critical exponents…
Breeding and Solitary Wave Behavior of Dunes
O. Duran, V. Schwaemmle, H. Herrmann
Beautiful dune patterns can be found in deserts and along coasts due to the instability of a plain sheet of sand under the action of the wind. Barchan dunes are highly mobile aeoli…
Scaling of the propagation of epidemics in a system of mobile agents
M. C. Gonzalez, H. J. Herrmann
For a two-dimensional system of agents modeled by molecular dynamics, we simulate epidemics spreading, which was recently studied on complex networks. Our resulting network model i…
