    摘要: A fast, conservative finite difference scheme for the full potential equation has been applied to the three- dimensional transonic flows. This scheme employes the standard approximate factorization ( AF2), upwind bias, temporal damping, and a specific .alpha.-sequence acceleration techniques. To achieve faster and more accurate results, an adaptive grid method using the tension and torsion spring analogies is also being developed. The resulting flow field calculations of half-span, full-span wing, and wing-body combination with different Mach numbers, angles of attack, and sideslip angles show the feasibility and validity of the current method.
