示踪剂质量浓度方程的简化及其隐式差分格式

Simplified tracer density equation and its implicit difference scheme

通过对示踪剂质量浓度方程的简化处理 ,给出了一种简化的数学模型 ,以及一种简化模型的隐式差分格式 .在对原模型结果影响甚小的前提下 ,利用此简化模型可减少计算量 .此外 。

In this paper, a simplified mathematical model on tracer density equation is given, and an implicit difference scheme on the model is derived. This difference scheme of the simplified model decreases the amount of calculation. Iteration algorithm of the difference scheme and selection of initial value are analyzed.
