Résumé :

Data on cylindrical free convection in water near 4°C are compared with a theory previously developed for a fluid having a density maximum. The main features of experimental curves are well reproduced by theory and it is shown that the typical temperature arrests observed in free cooling of water are due to the particular profile of the density which propagates from the boundary layer inside the bulk of the fluid (the central nucleus). Here, we report a density behavior shown by water in convective state. © 1993 The American Physical Society.
