Numerical Simulation of the Store Separation Using Unstructured Cartesian Grid

摘要

A new unstructured Cartesian gridrngeneration method is presented. The gridrngeneration of some airfoils and wing isrnperformed with the tree data structure.rnEuler equations are solved using therncell-centred finite volume method. Thernresults of flow field computation are inrngood agreement with the experiments.rnThese facts show that the grid generationrnand the numerical calculation approachrnare correct and reasonable.rnBased on the above work, a flowrnfield numerical simulation of wing andrnstore separation is finished. This processrnprovides a new way and tool for the morernaccurate solver of the unsteady flowrnproblem.
