A series of experiments are carried out with selective laser sintering(SLS) for copper,copper-nickel powder matetials.The phenomena of the sintering process is
An important aspect of the Orr-Sommerfeld problem, which governs the linear stability of parallel shear flows, is concerned with the study of the temporal and s
The incompressible Navier-Stokes equations are solved via variables of vorticity and velocity. Firstly, a rigorous variational framework with the equivalence be
