Development of An Efficient Three-Dimensional Tightly Coupled Euler/Potential Solver for Transonic Flow Analysis

摘要

The main purpose is to develop an efficient yet accurate tightly coupling method integrating Euler and potential flow solvers. In order to improve the efficiency while maintaining a good accuracy of the method, artificial boundary condition is introduced to reduce the domain size required for the far-field boundary condition. The coupled solver is validated in various flow cases around two-dimensional airfoil and three-dimensional wing. The validation result showed that the tightly coupled solver is valid in the various flow cases.
