Numerical simulation of 3D turbulent flow in equality screw-pitch Inducer 等螺距诱导轮的理论分析与数值模拟
The relationship between specific rotation of one kind cholesteric liquid crystal for CH-LCD and incidence wavelength, screw-pitch is simulated with the general cholesteric liquid crystal optical rotation theory and analyzed quantitatively. 利用旋光理论模拟了一种用于螺状相液晶显示器(CH-LCD)的螺状相液晶的旋光率与入射波长、螺距的关系,并从理论上给予定量分析;
Different screw-pitch and inner diameter ratios can affect the formation of the detonation wave. Steady and fully-developed detonation waves are successfully obtained when screw-pitch and inner diameter ratio is approximately 0.77, with the shortest deflagrate to detonation transition ( DDT) distance. 不同扰动螺纹螺距内径比对爆震波的形成有一定的影响,当螺距内径比约为0.77时可以产生稳定的、充分发展的爆震,而且对应的DDT距离较短。
