IGV의 유무에 따른 압축기의 성능변화

The present study describes the effects of IGV(inlet guide vane) on the internal flow of the rotor blades of a transonic axial compressor. Numerical solutions of the governing RANS equations for the three dimensional turbulent flows inside the compressor have been obtained by utilizing the ANSYS CFX program. The assessment of the IGV performance has been made by analyzing the numerical solutions of compressor and flow characteristics such as isentropic efficiency, total pressure, static pressure, incidence angle, and Mach number.
