Physics of Fluids | 1998

Paramagnetic liquid bridge in a gravity-compensating magnetic field

Milind P. Mahajan; Mesfin Tsige; P. L. Taylor; Charles Rosenblatt

Magnetic levitation was used to stabilize cylindrical columns of a paramagnetic liquid in air between two solid supports. The maximum achievable length to diameter ratio Rmax was ∼(3.10±0.07), very close to the Rayleigh–Plateau limit of π. For smaller R, the stability of the column was measured as a function of the Bond number, which could be continuously varied by adjusting the strength of the magnetic field.


Physics of Fluids | 1999

Stability of liquid crystalline bridges

Milind P. Mahajan; Mesfin Tsige; P. L. Taylor; Charles Rosenblatt

The stability of cylindrical bridges of the liquid crystal octylcyanobiphenyl in an immiscible liquid bath was investigated in the nematic and smectic A phases. In the nematic phase the bridge was found to destabilize at a length-to-diameter (slenderness) ratio R similar to that of ordinary Newtonian fluids. On the other hand, the Bingham behavior of the smectic A phase, i.e., an apparent yield stress, enabled the formation of stable columns with R well in excess of π.
