 Abstract: Multi-color Stochastic Rotation Dynamics (SRDmcSRDmc) has been introduced by Inoue et al. [1] ; [2] as a particle based simulation method to study the flow of emulsion droplets in non-wetting microchannels. In this work, we extend the multi-color method to also account for different wetting conditions. This is achieved by assigning the color information not only to fluid particles but also to virtual wall particles that are required to enforce proper no-slip boundary conditions. To extend the scope of the original SRDmcSRDmc algorithm to e.g. immiscible two-phase flow with viscosity contrast we implement an angular momentum conserving scheme (View the MathML sourceSRD+mc). We perform extensive benchmark simulations to show that a mono-phase SRDmcSRDmc fluid exhibits bulk properties identical to a standard SRD fluid and that SRDmcSRDmc fluids are applicable to a wide range of immiscible two-phase flows. To quantify the adhesion of a View the MathML sourceSRD+mc fluid in contact to the walls we measure the apparent contact angle from sessile droplets in mechanical equilibrium. For a further verification of our wettability implementation we compare the dewetting of a liquid film from a wetting stripe to experimental and numerical studies of interfacial morphologies on chemically structured surfaces.
