Molecular simulation for surface tension of new low GWP working fluids

In this work, the calculated surface tension of selected new low GWP (global warming potential) pure compound refrigerants HFO (hydro-fluoro-olefin) is presented. Molecular simulation methods are used to calculate the surface tension of R-1123 (trifluoroethylene) and of R-1234ze(E) (trans- 1,3,3,3-tetrafluoroprop-1-ene), as well as densities at saturation. The results obtained by molecular simulation are compared with recent experimental data.
