THE EFFECT OF CROSS-FLOW ON HEAT-TRANSFER AUGMENTATION WITH INTERRUPTED LONGITUDINAL FINS

Experiments were conducted with a shrouded array of interrupted fins w ith and without crossflow of air across the test section. The paramete rs varied during the steady-state experiments were the blowing rate an d power input. Friction factors and turbulence intensities were determ ined for both continuous and interrupted configurations. Average heat transfer coefficients and fin efficiencies were also determined and co nclusions made regarding the influence of crossflow on the pressure dr op and heat transfer rate of the interrupted fins.
