Abstract: | This paper reports experimental results on the propagation of a plane water jet at a temperature above the maximum-density temperature (4° C) along the free surface of initially quiescent water at a temperature of about 0°C. For comparison, experiments were performed in which the temperatures of the lower and higher layers were more than 4°C, other conditions being equal. The experiments revealed a number of new hydrodynamic effects, including peculiar flow instability and a fine structure of the density field at large times.Translated from Prikladnaya Mekhanika i Tekhnicheskaya Fizika, Vol. 46, No. 1, pp. 63–69, January–February, 2005 |
