Passage flow structure and its influence on endwall heat transfer in a 90 degree turning duct

he investigation considered the complex interaction between passage flow structure and endwall convective heat transfer in a square cross section, ;The three dimensional velocity field measurements indicate that a highly symmetric, strong secondary flow field developed with significant transfer of streamwise momentum to the transverse directions. The passage flow structure also contained regions of strong streamwise accelerations and decelerations, high vorticity, significant total pressure loss, and a complex turbulent flow field structure. The development of the pressure fields, the three dimensional velocity and vorticity fields, and the turbulent character of the...
