| dc.description.abstract | Steam turbines are an important component in steam power generation systems.
Steam turbines get tempered and high-pressure steam energy that expands through
the turbine spoon, so it is necessary to do steam flow analysis against the steam
turbine spoon with a circuit-crossed conductor spoon full of simulation methods.
This simulation is used to get the distribution of speed, pressure, and temperature
on the spoon. In this simulation, the turbine used is a one-tier steam turbine with
two lines. The researchers performed the simulation using the Fluent CFD
simulation application. The simulation used two types of steam: superheated and
saturated steam. Simulation results of the speed distribution of superheating and
saturating steam were averaged at 88.29 m/s and 81.79 m/s in the outlet area. The
pressure distribution simulation results on the simulation of superhigh and saturate
steam produced a pressure of 3.4 bar and 3.3 bar. And simulation result of the
temperature distribution in superheat and saturation steam with an average output
of 423.3 K and 419.3 K. In theoretical calculations, the distribution velocity of
Superheated & saturated steam was obtained at 143.9 m /s and 137.7 m/ s. The
average speed distraction values used simulation is smaller than in theoretic
calculations. It could be due to aerodynamic losses, like shock losses. The
percentage of errors from simulations and theoretical calculations on the speed
distribution of superheated and saturated vapour, were 38.64% and 40.61%. | en_US |
