High rotation number heat transfer of a 45° rib-roughened rectangular duct with two channel orientations

The effect of different inlet conditions of air in a rectangular channel on convection heat transfer: Turbulence flow

“…Methods of the PHE have been extensively explored with the attempts to overcome the thermal problems subject to high heat flux [4]. A variety of surface ribs [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], perforated baffle [22][23][24][25][26][27], pin-fins [28][29][30][31][32], Snail, propeller, twisted and winglet-type vortex generators [33,34,30,[35][36][37][38][39][40][41][42][43][44][45][46] have been devised to enhance heat transfer rates in ducts. However, it is shown in the literature review that detail exploration of turned flow in the channel needs more extensive study.…”

Wall modeled Large-Eddy Simulations in rotating systems for applications to turbine blade internal cooling

“…Liou et al [34] streamwise velocity profiles were overpredicted whereas wall-normal velocity profiles were underpredicted in simulations. However, spanwise velocity profiles showed reasonable agreements in the outer layer.…”

PIV flow measurements for a rotating square smooth channel heated by basically uniform heat flux

“…[2,3], and experimentally investigated in Refs. [4][5][6][7][8][9][10]. Both of investigators found that the mainstream velocity profile is pushed to trailing side by Coriolis force, and the turbulent Reynolds stresses are asymmetric.…”
