abstract = {<p style="text-align: justify;">Droplets on hydrophobic surfaces are ubiquitous in microfluidic applications
and there exists a number of commonly used multicomponent and multiphase
lattice Boltzmann schemes to study such systems. In this paper we focus on a popular
implementation of a multicomponent model as introduced by Shan and Chen. Here,
interactions between different components are implemented as repulsive forces whose
strength is determined by model parameters. In this paper we present simulations of
a droplet on a hydrophobic surface. We investigate the dependence of the contact angle
on the simulation parameters and quantitatively compare different approaches to
determine it. Results show that the method is capable of modelling the whole range of
contact angles. We find that the a priori determination of the contact angle is depending
on the simulation parameters with an uncertainty of 10% to 20%.</p>},
