A numerical study has been performed in order to investigate synthetic jet impingement on a flat plate for orifice-to-plate distances (H/d) of less than one. The aim was to show the effect of low H/d on heat transfer and flow field for a single circular orifice. Investigations have been done for frequencies of f = 250 Hz and 500 Hz, and 0.10 ≤ H/d ≤ 0.75. The results showed that at the stagnation region, the highest heat transfer values could be obtained for H/d = 0.75. On the other hand, more uniform temperature distributions have been observed for H/d = 0.10. Overall, this study provides guidance for the design of synthetic jet impingement cooling in small spaces with high thermal power densities.
