in this study, we proposed a novel scheme for the implementation of the no-slip boundary condition in thelattice boltzmann method (lbm) . in detail , we have substituted the classical bounce-back idea by the direct immersed boundary specification . in this way we construct the equilibrium density functions in such a way that it feels the no-slip boundaries . therefore , in fact a kind of equili...

The recently proposed concept of spring back reflectors has revolutionised the field of deployable antenna structures. The whole structure is made as a single piece from composite material, without any expensive and potentially unreliable joints, and it is simply folded elastically about a central axis, like a taco shell. Shape distortions occur during manufacturing and are difficult to correct...
