本文提出了一种有限体积框架下的三角多项式加权本质非振荡格式,以求解可能存在不光滑解的非线性退化抛物型方程.该方法基于零阶矩、一阶矩和二阶矩重构了三角多项式WENO格式,并采用直接间断Galerkin(DDG)通量来离散扩散项.此外,DDG方法直接将抛物型方程的弱形式应用于每个计算单元,有助于更好地捕捉解的特征,特别是间断解.同时,采用三阶TVD-龙格-库塔法进行时间离散化.最后通过数值测试评估所提方法的有效性和稳定性.
In this paper
we present a finite volume trigonometric weighted essentially non-oscillatory (TWENO) scheme to solve nonlinear degenerate parabolic equations that may exhibit non-smooth solutions. The present method is developed using the trigonometric scheme
which is based on zero
first
and second moments
and the direct discontinuous Galerkin (DDG) flux is used to discretize the diffusion term. Moreover
the DDG method directly applies the weak form of the parabolic equation to each computational cell
which can better capture the characteristics of the solution
especially the discontinuous solution. Meanwhile
the third-order TVD-Runge-Kutta method is applied for temporal discretization. Finally
the effectiveness and stability of the method constructed in this paper are evaluated through numerical tests.
