unsteady-state analysis improves

To improve the convergence behavior of the decoupled finite element method for the steady-state simulation of viscoelastic flow problems we introduced a modified unsteady term into the momentum and constitutive equations respectively To make sure an advantage of the new technique the eccentric flow problem of viscoelastic fluid was chosen by comparing stability of the simulations in the Numerical analysis of unsteady cavitation shedding dynamics around NACA66 hydrofoil by large-eddy simulation B Ji 1 2 K Miyagawa 1 X W Luo 2 Y L Wu 2 and H Y Xu 2 1 Applied Mechanics and Aerospace Engineering Waseda University Tokyo 169-8555 Japan 2 State Key Laboratory of Hydroscience Engineering Tsinghua University
