Transonic Potential Flow Calculations by Two Artificial Density Methods

A steady transonic flow over an airfoil is computed by solving the full potential equation discretized over a contour-fitting grid in full conservation form. Near shock waves, density is corrected to account for the rise in entropy in the region. A multigrid alternating direction method is used to drive the iteration. In supersonic flow regions, artificial dissipation is introduced by retarding...

Dynamical ‎C‎ontrol of Computations Using the Family of Optimal Two-point Methods to Solve Nonlinear ‎Equations

One of the considerable discussions for solving the nonlinear equations is to find the optimal iteration, and to use a proper termination criterion which is able to obtain a high accuracy for the numerical solution. In this paper, for a certain class of the family of optimal two-point methods, we propose a new scheme based on the stochastic arithmetic to find the optimal number of iterations in...

Advances in Turbulent Flow Computations Using High-resolution Methods

The paper reviews research activity in connection with the use of high-resolution methods in turbulent flow computations. High-resolution methods have proven to successfully compute a number of turbulent flows without need to resort to an explicit turbulence model. Here, we review the basic properties of these methods, present evidence from the successful implementation of these methods in turb...
