A series of benchmarks based on the physical situation of "phase inversion" between two incompressible liquids is presented. These benchmarks aim at progressing toward the direct numerical simulation of two-phase flows. Several CFD codes developed in French laboratories and using either Volume of Fluid or Level Set interface tracking methods are utilized to provide physical solutions of the benchmarks, convergence studies and code comparisons. Two typical configurations are retained, with integral scale Reynolds numbers of 1.37 10 4 and 4.33 10 5 , respectively. The physics of the problem are probed through macroscopic quantities such as potential and kinetic energies, interfa-cial area, enstrophy or volume ratio of the light fluid in the top part 1 arXiv:1906.02655v1 [physics.flu-dyn]
