RISHeat Transfer in a Rotating, Blade-Shaped Serpentine Cooling Passage With Discrete Ribbed Walls at High Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper experimentally investigates the effect of rotation on heat transfer in a typical turbine blade, three-pass, serpentine coolant channel with discrete ribbed walls at high Reynolds numbers. To achieve the high ...
Heat Transfer in a Rotating Cooling Channel (AR = 2:1) With Rib Turbulators and a Tip Turning Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental investigation on rotation and turning vane effects on heat transfer was performed in a two-pass rectangular internal cooling channel. The channel has an aspect ratio of AR = 2:1 and a 180 deg tip-turn, which ...
Heat Transfer in a Rib and Pin Roughened Rotating Multipass Channel With Hub Turning Vane and Trailing-Edge Slot Ejection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multipassage internal cooling test model with a 180 deg U-bend at the hub was investigated. The flow is radially inward at the inlet passage while it is radially outward at the trailing edge passage. The aspect ratio ...
