To achieve higher efficiency target of the advanced turbine systems, the closed-loop steam cooling scheme is employed to cool the airfoil. It is proven from the experimental results at laboratory working conditions that injecting mist into steam can significantly augment the heat transfer in the turbine blades with several fundamental studies. The mist cooling technique has to be tested at gas ...

Internal causes of impingement are secondary to rotator cuff and capsular dysfunction and are categorized by the location of the impingement and the underlying pathophysiological or mechanical cause of the impingement. These include posterosuperior impingement, anterosuperior impingement, anterior impingement, and entrapment of the long head of the biceps tendon. The objective of this article i...

Abstract Impingement jet heat transfer was studied using liquid and gas fluids to determine better cooling fluid. The materials used were rectangular steel plates of 230 mm by 120 12 mm, single diameters 10–40 with impingement gaps 115–155 mm. A computational fluid dynamics software application ANSYS 2020R1 employed for simulation, lumped thermal mass analysis experimental modeling. results sho...

This work reports the results of paired experiments for aft section a complex internal cooling flow within gas turbine vane using Magnetic Resonance Velocimetry (MRV) and steady-state Infrared (IR) thermography. The insert with two-pass impingement was designed at scale five times larger than original built stereolithography (SLA) fabrication methods. MRV technique used to measure three-dimensi...
