Nettet27. nov. 2013 · In this work, temporal and spatial linear stability analyses of a wind turbine wake are performed on a base flow obtained with time-averaged wind tunnel velocity measurements. This study shows that the low-frequency spectral component detected experimentally matches the most amplified frequency of the counter-winding … Nettet22. des. 2015 · This study is concerned with the numerical linear stability analysis of liquid-metal flow in a square duct with thin electrically conducting walls subject to a uniform transverse magnetic field. We derive an asymptotic solution for the base flow that is valid for not only high but also moderate magnetic fields.

Since stable and unstable equilibria play … Nettet28. jun. 2024 · Linear stability analysis is routinely applied to nonlinear systems to study how the onset of instability is related to system parameters and to provide physical insights on the conditions and early dynamics of pattern formation. 1–3 Some examples in hydrodynamics include the Orr-Sommerfeld equation that predicts the dependence on …
NettetThe linear stability of several classes of symmetrical relative equilibria of the Newtonian n-body problem are studied. Most turn out to be unstable; however, a ring of at least seven small equal masses around a sufficiently large central mass is stable. Nettet17. nov. 2024 · A fixed point, however, can be stable or unstable. A fixed point is said to be stable if a small perturbation of the solution from the fixed point decays in …

If a mechanical system is in a stable equilibrium state then a small push will result in a localized motion, for example, small oscillations as in the case of a pendulum. In a system with damping, a stable equilibrium state is moreover asymptotically stable. On the other hand, for an unstable equilibrium, such as a ball resting on a top of a hill, certain small pushes will result in a motion with a large amplitude that … ogre battle playstation
