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)
Impinging synthetic jets have been identified as a promising technique for obtaining high convective heat transfer rates in applications with confined geometries such as electronics cooling. Using a partially enclosed cavity with orifice, alternating fluid suction and ejection generate a periodic vortex train. This flow creates stronger entrainment of(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)
