Nonlinear ac responses of electro-magnetorheological fluids.
We apply a Langevin model to investigate the nonlinear ac responses of electro-magnetorheological (ERMR) fluids under the application of two crossed dc magnetic (z axis) and electric (x axis) fields and a probing ac sinusoidal magnetic field. We focus on the influence of the magnetic fields which can yield nonlinear behaviors inside the system due to the particles with a permanent magnetic dipo...
متن کاملThermal Conductivity of Square-Well Fluids
The thermal conductivity of a system consisting of square-well particles has been determined by the extension of the Enskog formula of the hard-sphere model to square-well fluid. The approach is the same as applied for the diffusion coefficients and shear viscosity of square-well fluid. The addition of an attractive part in the hard-sphere potential such as square-well potential remains insensi...
متن کاملBody Fluids
When thinking about fluid within the body we are essentially thinking about water. Tight regulation of the balance between water intake and output, and its distribution, is vital to the optimal function of every organ system within the body. In a wide variety of illnesses and during surgery, disturbances to this fine balance occur which must be identified and corrected to prevent deterioration,...
متن کاملOn Electro-kinetic Fluids: One Dimensional Configurations
Electro-kinetic fluids can be modeled by hydrodynamic systems describing the coupling between fluids and electric charges. The system consists of a momentum equation together with transport equations of charges. In the dynamics, the special coupling between the Lorentz force in the velocity equation and the material transport in the charge equation gives an energy dissipation law. In stationary...
متن کاملElectro-flow focusing: the high-conductivity low-viscosity limit.
Electro-flow focusing, a technique combining the features of electrospray (ES) and flow focusing (FF), provides a reliable tool to reach parametrical microjetting ranges not attainable by ES or FF alone under specific operational regimes (liquid properties and flow rate). In this Letter, we provide not only a closed theoretical model predicting the diameter of a high electrical conductivity ele...
