Abstract Al-Cu Nanocomposites (NCs) are widely used in industrial applications for their high ductility, light weight, excellent thermal conductivity, and low-cost production. The mechanical properties deformation mechanisms of Metal Matrix NCs (MMNCs) strongly depend on the matrix microstructure interface between second phase. present study relies Molecular Dynamics (MD) to investigate effects temperature elastic plastic behavior NC with single-crystal polycrystalline matrices. heating...
Abstract The CFD simulations in spacer-filled membrane modules reveal complex fluid structure diamond-type spacers as flow directional changes are seen due to inclined spacer filaments. Despite this behavior the remains steady for Reynolds number considered study. However, a parallel-type earlier thought be less complicated has shown three dimensionality well time dependency. Due transient nature, becomes asymmetric with flapping motion. eddies appear immediately behind transverse filaments,...
