Simulations of single and dual droplets in a uniform flow for Reynolds numbers 100 and Weber numbers of 0.1 and 1.0 are performed on a Cartesian grid using the Volume of Fluid method. The simulations are carried out to provide a detailed study of the interaction between droplets. Thus, the main focus is to investigate the forces a droplet is subjected to as its position is changed in relation to a reference droplet. The results are compared to simulations for solid particles using the Volume of Solid, a method based on the Volume of Fluid approach. The results show the importance of accounting to the full interaction among the droplets. Such interaction has to be included even for rather diluted two-phase systems. The large number of calculations results in a data-base that can be used as a look-up table for accounting for the inter-droplet interaction (i.e. effects on lift- and dragcoefficients) in the frame-work of Lagrangian particle tracking approach. Additionally, we do take into account also droplet deformation, which has significant effect for droplet in many engineering applications.
