...Kedar P. Nawathe; Aaditya R. Nath; Yong W. Kim; Terrence W. Simon Due to the proximity of the first-stage gas turbine vanes to the combustor, coolant introduced to the combustor walls interacts with the endwall film coolant and changes the vane passage flow physics. Recent results show...

..., it was shown in recent studies that combustor coolant introduced upstream of the vane passage changes secondary flow patterns in the passage. This results in a different secondary flow vortex system, called the “impingement vortex” system. It was discussed in recent literature having combustor coolant...
