Transverse Viscous Forces in Carr Walls and Possible Dynamic Consequences

Abstract

Expressions for the anisotropic viscous forces transverse to a nematic flow confined in a straight splay-bend wall are derived under simplifying assumptions. Some possible dynamic consequences, such as longitudinal splitting of the walls and movement of asymmetric walls in electro-hydrodynamic instabilities, are suggested. The relevance to recent experimental observations is discussed.
