摘      要：An extension of the standard Shan-Chen model for non ideal-fluids,catering for mid-range,soft-core and hard-core repulsion,is *** is shown that the inclusion of such mid-range interactions does not yield any visible enhancement of the density jump across the dense and light *** an enhancement can however be obtained by tuning the exponents of the effective *** results also indicate that the inclusion of soft-core repulsion can prevent the coalescence of neighborhood bubbles,thereby opening the possibility of tailoring the size of multi-droplet configurations,such as sprays and related phase-separating fluids.
