Finite Larmor radius stabilized Z-pinches [PDF]
, 1976 The possibility of Finite-Larmor-Radius stabilization of a straight, diffuse, Z-pinch is considered using the FLR corrected MHD fluid equations. Stabilization of all MHD modes is indicated if a/sub i//a is sufficiently large. If a/sub i//a is too large, however, current-driven instabilities are found. Comparison with several experiments suggests that a

The Effect of Rounding in Bump Foil Structure on the Dynamic Performance of Foil Journal Bearings
Tribology Online, 2019 The performance of air foil journal bearings is closely related to the stiffness of the bump foil. In this paper, the stiffness characteristics of bump foil having a rounding in the structure are investigated and compared with previous models.

Analytic expression for Taylor-Couette stability boundary
, 1996 We analyze the mechanism that determines the boundary of stability in Taylor-Couette flow. By simple physical argument we derive an analytic expression to approximate the stability line for all radius ratios and all speed ratios, for co- and ...

Stability of second-order differential inclusions
Electronic Journal of Differential Equations, 2011 For an arbitrary second-order stable matrix A, we calculate the maximum positive value R for which the differential inclusion $$ dot{x}in F_{R}(x):={(A+Delta)x, Delta in mathbb{R}^{2imes 2}, |Delta | leq R } $$ is asymptotically stable.

Stability of Liquid Bridges between Unequal Disks under Zero-Gravity Conditions [PDF]
, 1995 The stability, of axisymmetric equilibrium shapes of a liquid bridge between two coaxial disks of different radii under zero-gravity conditions is investigated. The stability regions have been evaluated for different values of the ratio of the disk radii
