Numerical 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 کاملA 2-D Numerical Investigation on the Modal Characteristics of Rotating-Stall with a Variable-Cascade- Length Approach in an Axial Compressor
The Rotating-Stall (RS) through a rotor-cascade of an axial compressor were numerically investigated with an unsteady two-dimensional finite-volume density based computer code. To validate the computer code, a test case was prepared and the good agreement of the compared results has given the adequate assurance of the code. The RS was incepted with a 40% reduction in flow coefficient and a 0.4%...
متن کاملStall Vortex Shedding over a Compressor Cascade (RESEARCH NOTE)
The unstable flow with rotating-stall-like (RS) effects in a rotor-cascade of an axial compressor was numerically investigated. The RS was captured with the reduction in mass flow rate and increasing of exit static pressure with respect to design operating condition of the single rotor. The oscillatory velocity traces during the stall propagation showed that the RS vortices repeat periodically,...

متن کاملComputational Study of Rotating Stall in High-Speed Compressor
A computational study of compressor instability based on body force representation of each blade-row of a transonic stage has been implemented for both clean inlet flow and flow with circumferential total pressure inlet distortion. The computational results indicate that many aspects related to compressor instability differ from what was observed in the experiment: steady compressor characteris...
