| Abstract | Steady plane flows of an electrically anisotropic polarizable liquid in a diverging metallic channel are studied. One of the channel walls is grounded while the other is kept at a high electric potential. The electrical anisotropy of the liquid is described by a unit vector whose direction is determined by a nonequilibrium relaxation equation. A dependence of the dielectric polarization on the electric field strength and anisotropy vector is determined by an equilibrium relationship. Such a model may correspond to a suspension of polarizable fibers in a dielectric liquid. The exact self-similar solution to the formulated governing equations is obtained. Distributions of the liquid velocity, pressure, polarization, anisotropy vector, and electric field in the channel are found and examined. As with the vanishing electric field, there is a critical value of the Reynolds number at which the reverse flow starts at the channel walls. The dependence of the critical Reynolds number on the liquid properties and channel characteristics is found. In particular, the presence of a sufficiently strong electric field between the channel walls leads to a rise in the critical Reynolds number. Thus, the flow of anisotropic dielectric liquid in a diverging channel can be controlled by electrical means. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
