Numerical 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...
متن کاملLife Estimate of a Compressor Blade through Fractography
Failure analysis of fractured components provides some information about the causes and conditions of fracture. Fractography is an indispensable part of the failure analysis as it is usually the only means by which the failure mechanism can be established. By using fractography, some information such as component’s life, values of the stress intensity factor and the applied stress can be calcul...
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 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,...
