摘要

本文提出了一种标量传输方程的限制技术。该方法的独创性在于它不需要解决非线性优化问题，也不依赖于低阶近似的构建。该方法的复杂性极低，并在数值上保持了高阶精度。该方法的性能在辐射传输方程中得到了说明。

Mass conservative limiting and applications to the approximation of the steady-state radiation transport equations

A limiting technique for scalar transport equations is presented. The originality of the method is that it does not require solving nonlinear optimization problems nor does it rely on the construction of a low-order approximation. The method has minimal complexity and is numerically demonstrated to maintain high-order accuracy. The performance of the method is illustrated on the radiation transport equation.

期刊介绍： Journal of Computational Physics thoroughly treats the computational aspects of physical problems, presenting techniques for the numerical solution of mathematical equations arising in all areas of physics. The journal seeks to emphasize methods that cross disciplinary boundaries. The Journal of Computational Physics also publishes short notes of 4 pages or less (including figures, tables, and references but excluding title pages). Letters to the Editor commenting on articles already published in this Journal will also be considered. Neither notes nor letters should have an abstract.
