An elliptic curve random number generator (ECRNG) has been proposed in ANSI and NIST
draft standards. This paper proves that, if three conjectures are true, then the ECRNG is secure.The three conject...
关于RNG代数湍流模式的研究
RNG代数模型 涡黏性 湍流
2007/7/28
摘要研究了RNG代数湍流模型,提出的涡黏性方程根的识别方法对涡黏性的选择给予了合理的物理意义,它减少了模型使用中的经验性,缩短了计算时间。另外关于用外部涡函数的双峰平均法来确定分离区附近边界层的厚度也是有意义的,它继承了BaldwinLomax代数模型的长处,改进了其不足,可用于分离流动的工程计算.
用RNG K-E模式数值模拟180°弯道内的湍流分离流动
RNGK-ε湍流模式 湍流分离流动 强曲率道 任意曲线坐标系 协变分量
2007/7/28
摘要将Yakhot与Orszag新近提出的RNGK-ε湍流模式推广应用于180°强曲率弯道内的湍流分离流动的数值模拟,计算在任意曲线坐标下进行,并采用速度协变分量作为求解变量以保证计算的高度稳定性,控制方程的求解采用通常的控制容积法,文中给出了详细的数值计算结果,并与实验结果进行了比较,结果表明,RNGK-ε湍流模式能有效地模拟有强曲率影响的湍流分离流动,展示了这一模式在工程湍流计算中的前景
