Accurate mechanistic modelling of a complex system requires insight into the process being simulated, in addition to a theoretical 'first-principles' approach. The current work uses a numerical mechanistic model to simulate dissolution of a particulate system in the flow-through dissolution apparatus. A shadowgraph imaging method is also used to monitor the(More)
 We identify technological drivers for tomorrow’s data centers and telecommunications 14 systems, including thermal, electrical and energy management challenges, based on discussions at the 15 2nd Workshop on Thermal Management in Telecommunication Systems and Data Centers in Santa Clara, 16 California, on April 25-26, 2012. The relevance of thermal(More)
Synthetic jets are a relatively new technology and have shown great promise in a number of practical applications such as flow control through active boundary layer mixing and enhanced heat transfer through forced convection. It has been shown by Kercher et al. (2003) that synthetic jets can deliver similar cooling effects to conventional steady flow(More)
The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable particle displacement. Various techniques have extended the dynamic range, however flows with a wide velocity range (e.g., impinging jets) still challenge PIV algorithms. A new technique is presented to increase the dynamic velocity range by(More)
The thermoacoustic effect that results from the interaction of a sound wave in a compressible fluid in contact with solid boundaries is known to be capable of removing heat from power dissipating systems. In this paper the standing wave acoustic field that is generated in an open ended duct, a section of which is heated, and how it interacts with the(More)
The exploitation of flow unsteadiness in microchannels is a potentially useful technique for enhancing cooling of future photonics systems. Pulsation is thought to alter the thickness of the hydrodynamic and thermal boundary layers, and hence affect the overall thermal resistance of the heat sink. While the mechanical and thermal problems are inextricably(More)
The implementation of synthetic jets for use in the cooling of electronics is a relatively new technology. Steady flow impinging jets can produce relatively high heat transfer coefficients; however it has been shown by Kercher et al., (2003) that synthetic jets can deliver similar cooling effects without the need for an air supply system. Impinging(More)
