We present here both analytical and numerical results of hydrodynamic stability investigations of rota-tionally supported circumstellar flows using the shearing box formalism. Asymptotic scaling arguments justifying the shearing box approximation are systematically derived, showing that there exist two limits which we call small shearing box (SSB) and large shearing box (LSB). The physical mean...
Static friction in shearing mode can be expressed as the product of the shear strength of the interface and the real contact area. The influence of roughness on friction in elastic adhesive contact is analyzed. Special attention is paid to low loading conditions, in which the number of contact points is small. The models are used to analyze a friction experiment in a MEMS friction meter.
Abstract. Statistical parameters of the ISM driven by thermal energy injections from supernova explosions have been obtained from 3D, nonlinear, magnetohydrodynamic, shearing-box simulations for spiral arm and interarm regions. The density scale height obtained for the interarm regions is 50% larger than within the spiral arms because of the higher gas temperature. The filling factor of the hot...
electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...
