“…Shih and Sultanian [20], gave a review on computations of internal and film cooling in gas turbines. Rigby [21] used k-omega turbulence model with concentration on grid structure to describe heat transfer in a ribbed channel with 180 deg bend and showed reasonable agreement with experimental results of Park et al [22]. Prakash and Zerkle [23] performed a computation of rib-roughened rotating duct neglecting buoyancy-centrifugal effect.…”

“…Investigations which employ naphthalene sublimation to determine mass transfer generally obtain results which are consistent with heat transfer experiments [216,[238][239][240][241][242][243][244][245][246][247]. However, one drawback of such mass transfer methods is the absence of buoyancy within experiments.…”

To provide an overview of the current state of the art of heat transfer augmentation schemes employed for internal cooling of turbine blades and components, results from an extensive literature review are presented with data from internal cooling channels, both with and without rotation. According to this survey, a very small number of existing investigations consider the use of combination devices for internal passage heat transfer augmentation. Examples are rib turbulators, pin fins, and dimples together, a combination of pin fins and dimples, and rib turbulators and pin fins in combination. The results of such studies are compared with data obtained prior to 2003 without rotation influences. Those data are comprised of heat transfer augmentation results for internal cooling channels, with rib turbulators, pin fins, dimpled surfaces, surfaces with protrusions, swirl chambers, or surface roughness. This comparison reveals that all of the new data, obtained since 2003, collect within the distribution of globally averaged data obtained from investigations conducted prior to 2003 (without rotation influences). The same conclusion in regard to data distributions is also reached in regard to globally averaged thermal performance parameters as they vary with friction factor ratio. These comparisons, made on the basis of such judgment criteria, lead to the conclusion that improvements in our ability to provide better spatially-averaged thermal protection have been minimal since 2003. When rotation is present, existing investigations provide little evidence of overall increases or decreases in overall thermal performance characteristics with rotation, at any value of rotation number, buoyancy parameter, density ratio, or Reynolds number. Comparisons between existing rotating channel experimental data and the results obtained prior to 2003, without rotation influences, also show that rotation has little effect on overall spatially-averaged thermal performance as a function of friction factor.

“…Heat transfer experiments have been presented detailing measurements in ducts similar to those in all three regions of the present study, including developing flow (Han and Park, 1988;Liou and Hwang, 1992a;Wagner et al, 1992;Wang et al, 2001;Chang and Morris, 2003), fully developed flow (Han, 1984;Liou and Hwang, 1992b;Baughn and Yan, 1992;Fann et al, 1994;Park et al, 1998;Mochizuki et al, 1999;Ekkad et al, 2000;Chen et al, 2000;Islam et al, 2002;Rau et al, 1998), and flow in the 180°b end region . In addition, flow measurements in the fully developed region have been obtained using LDV measurements (Rau et al, 1998;Sato et al, 1989;Liou et al, 1993a;Graham et al, 2004) and hot-wire anemometer measurements (Hirota et al, 1992).…”
