In this section we use DPD simulations to determine the interfacial tension and surface energies that are required in the Young equation, Eq. ( ), using the volume-average pressure tensor components in Eq. ( ) as detailed above. We convert the results from DPD units to real units by multiplying by the factor k B T /r 2 c = r c × RT /N A r 3 c ≈ 12.9 mN m -1 , on the basis of Eq. ( ) and assuming T = 298 K.
