One-Dimensional design of a three-stage axial compressor with Its 3D numerical simulation
The purpose of this study is to design a three-stage axial compressor with identical pressure ratio which makes an adequate pressure ratio and efficiency in design point conditions with rotational velocity of 38000rpm and mass flow rate of 3.2kg/s. First of all, considering some restrictions such as Dehaller number more than 0.7 in all sections of the stator and the rotor, and relative Mach num...

متن کاملNumerical Investigation of Rotating-Stall in a Stage of an Axial Compressor with Two Different Approaches
An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters and the two-layer Baldwin-Lomax turbulence model was also implemented. To validate the solver, two test cases were prepared and the computed results had good agreements with reference data. The rotating...
متن کاملNumerical Simulation of Dynamic Stall Phenomena in Axial Flow Compressor Blade Rows
This article explores the simulation of stall phenomena in axial compressor blade rows. The approach is based on the numerical solution of the compressible, two-dimensional Navier-Stokes equations. The results of both unforced and forced low-speed rotor stall are presented. In unforced cases, substantial ow separation is observed before the maximum pressure rise operating point is reached. Thes...
