Micropumps can play a significant role in thermal management applications, as a component of microfluidic cooling systems. For next-generation high density Photonics Integrated Circuits (PICs), in particular, heat flux levels are sufficiently high to require a microfluidic circuit for cooling. Valveless piezoelectrically- actuated micropumps are a particularly promising technology to ...

  • Jeffers N.
  • Stafford J.

Piezoelectric fans are receiving increased interest for thermal management applications because of their reliability, minimal power consumption, and noise-free operation. These features are of particular interest to companies who have strict reliability constraints and have reached the thermal limit of conventionally used natural convection heat sinks. For a classical piezoelectric ...

Geometric structure of segmented flow networks

  • Jeffers N.
  • Stafford J.

Segmented flows consist of two immiscible fluids which travel along a channel in a segmented arrangement due to an imposed pressure difference. In this paper, the geometric structure of segmented flow networks is examined and fundamental design rules are established for two-phase flow without phase change. These rules provide a ...
