In this talk I will review our recent attempts to develop new simulation models based on combined lattice Boltzmann and Molecular Dynamics methods to simulate the behavior of blood flow or colloidal particles at liquid interfaces. In the case of blood flow we have demonstrated that our model is able to bridge the gap between common microscopic models describing individual cells in detail and macroscopic models based on standard CFD. Colloidal particles can be used as an alternative to stabilize emulsions with the advantage of a complete blocking of Ostwald ripening and long-term stabilization. I will show simulation results demonstrating the similarities and differences between particles and surfactants and demonstrate the properties of large scale phases such as Bijels and
Pickering emulsions.
