Modeling of Smart Materials of Nanostructure in a Poorly Electrically Conducting Fluid Saturated Composite Materials

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).
