Moving contact lines are implemented in a volume-of-fluid scheme with piecewise linear interface construction. Interfacial tension is treated as a continuous body force, computed from numerical derivatives of a smoothed volume-of-fluid function. Two methods for implementing the contact angle condition are investigated. The first extrapolates the volume-of-fluid function beyond the flow domain, ...

Swimmers in nature use body undulations to generate propulsive and manoeuvring forces. The anguilliform kinematics is driven by muscular actions all along the body, involving a complex temporal and spatial coordination of all the local actuations. Such swimming kinematics can be reproduced artificially, in a simpler way, by using the elasticity of the body passively. Here, we present experiment...

For multiclass queueing networks, dispatch policies govern the assignment of servers to the jobs they process. Production policies perform the analogous task for queueing networks whose servers are subject to switch-over delays or setups, a model we refer to as setup networks. It is well known that a poorly chosen dispatch policy may lead to instability of a multiclass queueing network, even wh...
