Modeling of Smart Materials of Nanostructure in a Poorly Electrically Conducting Fluid Saturated Composite Materials
Abstract:
To meet the demands of technology for the development of new materials with tailormade properties, we propose the use of smart materials of nanostructure synthesized by solidifying a poorly conducting alloy in a microgravity environment in the presence of an electric field and surface tension. Energy method combined with a single term Galerkin expansion is used to find the condition for the onset of Marangoni marginal electroconvection (MMEC) in a composite material modeled as a porous layer. It is shown that a proper choice of electric parameter and the ratio of Brinkman viscosity to viscosity of the fluid λ control Marangonielectroconvection (MEC).
