[4] The analysis of behavior of a massive gravitational fencing caisson at its incrementing and plunging into heterogenenous soil milieu allowed identifying the nature of its non-linear and unsteady behavior.

[6] This unsteady behavior of the flow is then characterized by using time-dependency signal of spatially averaged Nusselt number on the hot wall and its corresponding frequency analysis. [7] The results showed that the proposed model could reproduce the unsteady behavior of the CVRC predicted by the high-fidelity simulation reasonably well. [8] Unsteady behaviors are important issues in flow control of turbomachinery. [9] The main attention is focused on the unsteady behaviors of coherent structures, which determine the film cooling efficiency. [10] ABSTRACT The unsteady behavior of fluid flow such as pressure variation and fluctuation in a hydraulic turbine may lead to operational instability. [11] The methodology used to characterize the shock behavior in solid materials may be inappropriate for granular materials because of this unsteady behavior and interactions between the granular material and measurement surfaces. [12] , the unsteady behavior of the impinging synthetic jet. [13] This article describes an investigation of the unsteady behavior of turbocharger turbines by one-dimensional modeling and experimental analysis. [14] The instantaneous and time-average contours of isotherms and streamlines were used to study the unsteady behavior of the flow.

[17] In this study, the unsteady behavior of impulse turbine under various constant-flow conditions is investigated. [18] Finally, the unsteady behaviors of hydrodynamics of this HAMHRT were analyzed farther. [19]本文针对时间相关的扩散彼得林粘弹性模型提出并分析了一种一阶线性化压力校正投影方法,该方法可以描述一些不可压缩聚合物流体在二维上的非定常行为。 [1] 自由表面涡旋具有不稳定的行为,因为它的位置和持续时间急剧变化。 [2] 从准定常流动行为到非定常行为的转变发生在大约 Sr = 0 时。 [3] (2011) 提出了一个半经验数学模型来模拟冰箱中往复式压缩机的非稳态行为。 [4] 对大型重力围栏沉箱在其增加和陷入异质土壤环境时的行为进行分析,可以确定其非线性和不稳定行为的性质。 [5] 在这项工作中,提出了一种预测柔性螺旋桨非定常行为的数值方法。 [6] 然后通过使用热壁上空间平均努塞尔数的时间相关信号及其相应的频率分析来表征流动的这种不稳定行为。 [7] 结果 表明所提出的模型可以重现 CVRC 通过高保真模拟预测得相当好。 [8] 非定常行为是涡轮机械流动控制中的重要问题。 [9] 主要关注点集中在决定薄膜冷却效率的相干结构的不稳定行为上。 [10] 摘要 流体流动的不稳定行为,例如水轮机中的压力变化和波动,可能会导致运行不稳定。 [11] 用于表征固体材料中的冲击行为的方法可能不适用于粒状材料,因为这种不稳定的行为以及粒状材料和测量表面之间的相互作用。 [12] ,撞击合成射流的不稳定行为。 [13] 本文介绍了通过一维建模和实验分析对涡轮增压器涡轮的非稳态行为进行的研究。 [14] 等温线和流线的瞬时和时间平均轮廓用于研究流动的非定常行为。 [15] 还研究了热力学和流体动力学的非定常行为对传热现象的影响。 [16] ICE-CFD 求解器用于检查实际发动机配置的不稳定行为。 [17] 在这项研究中,研究了脉冲涡轮在各种恒流条件下的非定常行为。 [18] 最后,进一步分析了该HAMHRT流体动力学的非定常行为。 [19]
