Structure of electrorheological fluids under an electric field and a shear flow: experiment and computer simulation.
It is known that macroscopic properties of colloidal suspensions are often determined by the microstructure of the particles in the suspensions, depending on the interparticle, Brownian, and hydrodynamic (if any) forces. We take electrorheological (ER) fluids as an example. By using a computer simulation and an experimental approach, we investigate the structure of ER fluids subjected to both a...
متن کاملUnidirectional compression of electrorheological fluids in electric fields
A series of unidirectional compression tests on electrorheological fluids has been carried out with different plate sizes, initial plate separations, and applied voltages. Experimental results of compression pressure were compared with the continuum non-Newtonian squeeze-flow theory in a normalized form. It was found that the compression resistance of the electrorheological fluid in an electric...

Mechanical properties of electrorheological uids under various dynamical loading conditions have been studied using a computer simulation model. The model assumes electrostatic point-dipole interaction between particles with or without multipolar corrections and the interaction with the base uid due to viscous laminar ow is described with Stokes drag. The mechanical loading is introduced as con...
متن کاملStatic shear modulus of electrorheological fluids.
We report measurements of the static shear modulus of electrorheological (ER) fluids consisting of water-wetted silica microspheres in silicone oil. A shear-annealing method, using creep-recovery (CR) cycles under an external electric field, is used to enhance ER properties of the fluid. The shear-annealing method enables the silica spheres in the ER fluid to form better aligned and denser colu...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
