Fluid-Structure Interaction in Aluminum Extrusion
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with a very high...

Nonlinear Magnetostrictive Transducer
Magnetostrictive transduction is used in sonars, acoustic devices, active vibration and position control and fuel injection systems.
The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the core which works as an actuator when a magnetic field i...

Spontaneous Phase Separation of Immiscible Fluids
Phase separation occurs when a binary system is quenched from its stable, homogeneous one-phase state into the two-phase region of its phase diagram. The spontaneous separation of two immiscible fluids is sometimes referred to as spinodal decomposition. Each phase tends to separate into pure...
