摘要
本文采用近似因式分解(AF2)方法,数值求解二元跨音速小扰动速势方程。大量的数值实验表明:1.选取不同的松驰因子或加速收敛参数可能得到不唯一解。2.选取不同的初场,无论是采用Murman-Cole守恒或非守恒格式,还是采用Engquist-Osher格式,都可能得到不唯一解。
An implicit approximate factorization scheme(AF2) is employed in this paper to obtain the numerical solutions of TSD and TSTD equation.the numerical experiments show that:1.the solutions are nonunique for different initial φ.2.the solutions are nonunique for different relaxation factors or different accelerate parameters.
