这一提法解决非线性问题,表面上的边界插值这些要素和影响之间的界限。
This formulation solves the non-linear problem on the surface of the boundary elements and interpolates these effects between these boundaries.
由于采用了非线性混合边界元,故本文所提出的方法精度高,简单易行,计算量小,可以较广泛地适用于偏离设计工况的运行情况,算例结果同实验值吻合很好。
A nonlinear mixed boundary element method is used here. And this method can be easily extended to off design conditions. The calculated results agreed very well with experimental data.
最后我们研究了初始边界值问题。 通过数值试验证明,线性正弦波会逐步变为非线性的圆锥型波。
At last an initial-boundary value problem was considered and the numerical experiment demonstrated that the linear sinusoidal wave would successively evolve non-linearly into conoidal wave.
