... that in the Reynolds number range of 1678–8500, the pin fin channel with transverse spacing-to-diameter of 1.5 has a higher convective heat transfer performance, but the enhancement capability decreases with the Reynolds number. For Re <6000, the overall thermal performance of the pin fin channel with transverse...

... in-passage convective heat transfer enhancements caused by thin boundary layers and impinging flows in the vicinity of the intersections would improve total heat flux (Watts per square meter) despite surface area lost to intersection voids. As the heat transfer and loss enhancements do not rely...

... Dimpled surfaces may be considered for heat transfer enhancement in internal cooling of gas turbine airfoils. In this study, convective heat transfer and pressure drop for turbulent airflow in a square channel with a dimpled wall were examined. Experiments were conducted to determine the average...
