Systematic measurements on the heat transfer and pressure loss performance of pin-fin arrays were conducted using a wind tunnel, by varying the pin pitch as a parameter. The pin-fin arrays used in the present study were made of square shaped thin pins arranged densely in a rectangular form. The modified single blow transient testing method was applied to the measurement. Additionally, the flow visualization tests were carried out utilizing fifteen times enlarged pin-array models with dye injection technique. Water was used as the test fluid. The test results showed a good correspondence between the heat transfer and pressure loss phenomena and the flow pattern characteristics.
