Turbine section components include the turbine rotor, turbine shell, nozzles, shrouds , exhaust frame and exhaust diffuser.

EthosEnergy offers complete in-house manufacturing cycles for all stationary parts such as Nozzle and Shrouds from the casting condition to the final.

High Velocity Oxy- Fuel (HVOF) deposition process. Air is compressed by the fan blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor fan blades.

Generally speaking, main flow path of gas turbine is assumed to be perfect for standard 3D computation. But in real engine, the turbine annulus geometry is not completely smooth for the presence of the shroud and associated cavity near the end wall. Besides, shroud leakage flow is one of the dominant sources of . These shrouds have an internal perforated box which improves cooling to inner side walls of shroud. An inner seal plate groove is formed on the outer circumference of the hook formed on . Unshrouded blades of axial turbine stages move in close proximity to the stationary outer seal, or shroud , of the turbine housing.

The effect of inlet boundary layer thickness as well as rotation rate on the tip and shroud heat . Reynolds Averaged Navier-Stokes equations.

Numerical investigations of flow structure in gas turbine shroud gap. Interdepartmental PhD Studies at the Gdansk University of Technology Narutowicza. The structure of the flow in the labyrinth sealing of an axial gas turbine was investigated by means of numerical simulations.

Additionally, the flow structure for two- and three-dimensional axisymmetric models was compared. In order to minimize load transfer between the shroud ring and the turbine casing the shroud ring is radially supported by and radially spaced apart from . The method entails removing the oxidation and corrosion products from the shroud segment, . In addition, an air shroud surrounding the nozzle, .
