Abstract
The artificial damping and compressibility method (ADC) is a rapid numerical technique for solving steady three-dimensional incompressible and compressible Navier-Stokes equation. The principle of this method lies in the introduction of an artificial damping factor into the group of linear equations, by which the elliptic equation is replaced, and the final results do not depend on the artificial terms. The consistency of this method for viscous flow is proved theoretically. The advantages of the SMAC method, the artificial compressibility method and the dynamic relaxation method are retained in the ADC method. Sample calculation of a bending jet is included. The results show that the convergence rate for calculating three-dimensional elliptic flow problems increases by 3–4 order of magnitude as compared with the SOR method.
