辐射流体力学的分子动理学自适应加密方法(英文)被引量:1
《计算物理》2015年第3期277-292,共16页孙文俊 范征峰 
Supported by NSFC(11371068,11001026,10971016,40890154,91130020)
通过构造新的平衡分布函数和结合分区自适应网格加密方法,对不带扩散项的平衡辐射流体力学方程,构造二阶的分子动理学BGK-AMR格式.一方面在关心的计算区域中局部加密计算网格,提高计算精度的同时大大节省了计算网格数量和计算时间;另一...

辐射流体力学的压力解耦BGK分子动理学方法(英文)
《南京师大学报(自然科学版)》2013年第4期5-13,共9页孙文俊 倪国喜 
Supported by the National Natural Science Foundation of China(11001026,11371068,10971016,40890154,91130020)
本文通过一个物质压力和辐射压力解耦的分子动理学BGK模型,设计了辐射流体力学方程的分子动理学数值格式.该格式有两方面的优点,一方面,由于BGK模型中流体压力和辐射压力的解耦,因而物质压与辐射压的作用可以解耦,微观方程与宏观方程间...

A NON-OSCILLATORY KINETIC SCHEME FOR MULTI-COMPONENT FLOWS WITH THE EQUATION OF STATE FOR A STIFFENED GAS被引量:2
《Journal of Computational Mathematics》2011年第6期661-683,共23页Yibing Chen Song Jiang 
We extend the traditional kinetic scheme for ideal gases to the Euler equations with the equation of state for a multi-component stiffened gas. Based on a careful analysis of the oscillation mechanism of the tradition...
