Abstract: Abstract Complex fluids are common in our daily life and play an important role in many industrial applications. The understanding of the dynamical properties of these fluids and interfacial effects is still lacking. Computer simulations pose an attractive way to gain insight into the underlying physics. In this report we restrict ourselves to two examples of complex fluids and their simulation by means of numerical schemes coupled to the lattice Boltzmann method as a solver for the hydrodynamics of the problem. First, we study Janus particles at a fluid-fluid interface using the Shan-Chen pseudopotential approach for multicomponent fluids in combination with a discrete element algorithm. Second, we study the dense suspension of deformable capsules in a Kolmogorov flow by combining the lattice Boltzmann method with the immersed boundary method.
