The advantages of labyrinth–honeycomb seals in turbomachines are widely increasing the usage them. In this investigation, a numerical study has been done to simulate seal which is commonly used rotor blade tip. Three-dimensional simulation performed by ANSYS-CFX. Simulation results show good agreements with experimental data. To have better understanding flow behavior within seal, set sensitivity analyses on geometry parameters carried out. First, smooth plate replaced honeycomb and...
This paper describes the procedure for developing a new airfoil family. family applies to heavy-duty, industrial, and aero-derivative gas turbine compressors ranging from subsonic transonic flow regimes. The is generated by filling database with optimized geometries. structured in six dimensions, called design space parameters, including inlet Mach number, angle, outlet axial velocity density ratio, maximum thickness chord solidity. six-dimensional includes all compressor blades used...
This paper presents a design approach aimed at improving the performance of gas turbines in hot ambient temperature conditions by optimizing axial compressor. The objective project was to increase output power two heavy-duty generation 8%. optimization process involved re-staggering compressor stator blades and implementing end-bend elliptic leading edge technology ensure stability efficiency. An tool utilized determine optimal configuration re-stagger angles, which then evaluated using...
To achieve at a more precise designing procedure in axial-compressors as well higher pressure ratio value, comprehensive understanding on the flow aerodynamics and governing phenomena is required. Existence of these complicated e.g., simultaneous production supersonic subsonic flows, shock-boundary layer interaction, unique incidence phenomenon, etc, makes it difficult to analyze transonic compressors. One methods which useful modeling occur compressors investigating blade passage. In this...
This paper investigates the results of a frequency analysis performed on blades last three compressor stages two different gas turbines (Case A and B). The axial compressors in B have ten eleven stages, respectively. studied identical number both compressors. However turbine has higher upstream vanes before each rotating stage. Turbine is actually modified version with power output. manufacturer provides acceptable ranges for several natural frequencies stage No.8 to 10 case A. One purposes...
