...Nathaniel J. Tracy; Lesley M. Wright; Je-Chin Han Friction loss and heat transfer enhancement measurements were obtained for double-sided, partial height, strip fin arrays in a high aspect ratio (AR = 8), rectangular channel. Fins were arranged in a staggered array configuration with channel height...

... by thermochromic liquid crystal (TLC) of the same geometry. Lower-order large-scale fluctuation and higher order small-scale disturbances were examined separately using Proper Orthogonal Decomposition (POD) to study the flow field characteristics and their individual effect on the heat transfer enhancement. Pin...

... increase with the Reynolds numbers, which means that the swirl multi-pass channel has higher heat transfer enhancement capability at a higher Reynolds number. The circumferentially uniform heat transfer characteristic of swirling flow also performs well in this study. The high and circumferentially uniform...

... is modified by off-setting one leg of the V to create a staggered discrete, V-shaped configuration. The ribs are oriented 45 deg relative to the streamwise coolant direction. The heat transfer enhancement and frictional losses are measured with varying Reynolds and rotation numbers. The Reynolds number varies...

... facility. After identifying the inherent acoustic resonance frequencies of the passageways, the impact of excitation is studied in various sound pressure levels, blockage ratios, as well as Strouhal and Reynolds numbers. The acoustic resonance excitation resulted in heat transfer enhancement of 20% and 10...

... show extensive heat transfer enhancement as a function of extraction angle and suction ratio in the near-hole region and demonstrate good agreement with a corresponding study. Furthermore it was shown that the effect of a wall-to-coolant ratio is of a second order and can therefore be considered...
