Blade tip cooling
WebActive tip-clearance control. Active clearance control ( ACC) is a method used in large aircraft gas turbines to improve fuel efficiency during cruise. This is achieved by setting the turbine tip clearance at more than one operating point and contrasts with passive clearance control which sets it for only one condition and is explained below. WebThe cooling air, which is 0.3 % of the total mass-flow, appears to be well mixed with the leakage flow and makes little differenceto the flow field downstreamof the ro- ... (b1) …

Some of the water in the blade can be allowed to vaporize, thus taking advantage of the heat of vaporization to lower coolant-flow requirements. At the stationary shroud a collector catches the unvaporized water that is slung from the blade tip. The ejected steam
WebJan 1, 2024 · Film-cooling is typically used as a blade tip cooling method, whereby coolant is supplied through holes placed along the pressure side of a blade. Experiments were conducted in a linear cascade ... WebA turbine blade includes an airfoil having an internal cooling circuit therein. The airfoil extends from a root to a tip cap, and includes laterally opposite pressure and suction sides extending between a leading edge and an opposite trailing edge over which is flowable a combustion gas. A pair of squealer tips extend radially upwardly from the tip cap along …
