摘要：

The paper studies a performance of a preconditioned iterative method applied to solve the linearized Navier-Stokes system. We try BiCGstab algorithm and discretized the problem by a stabilized finite element method. Essential for building a good preconditioner is the rotation form of the original PDE system. Numerical results demonstrate the robustness of the method.
