Abstract We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a solid nucleus (IN<inf>M</inf>) for M = 48, 56, 64, 72, 80 and 90 molecules, and the rest were arranged in liquid state. By using a statistical analysis, we determined the nucleation rate (j<inf>M</inf>) for systems formed with IN<inf>64</inf>, IN<inf>72</inf>, IN<inf>80</inf> and IN<inf>90</inf>. These results are coherent with the stochastic hypothesis for heterogeneous nucleation and show a direct relationship between M and j<inf>M</inf>.
