With this proposal we apply for CPU time on the HLRS NEC SX8 machine in order to use our lattice Boltzmann code LB3D to simulate liquid crystals, sheared binary fluid mixtures and microfluidic systems. Liquid crystals: we are interested in the formation of the gyroid mesophase and the development and influence of defects in these phases. Sheared fluid mixtures: Sheared fluid mixtures have many industrial applications and are still not fully understood. We plan to simulate binary and ternary mixtures in order to reproduce structuring effects, shear thinning and other rheological effects. Microfluids: in very small channels, the no slip boundary condition is not valid anymore, but a so call wall slip occurs. We are planning to develop new boundary conditions for our method and to study their applicability. LB3D has been successfully ported and tested to the SX8 already.
