摘要

An experimental and numerical investigation is presented concerning the natural convec- tion of water near its maximum-density in a differentially heated rectangular enclosure at high Rayleigh numbers, in which an oscillatory convection regime may arise. The water in a tall enclosure of A_y=8 is initially at rest and at a uniform temperature below 4 deg C and then the temperature of the hot vertical wall is suddenly raised and kept at a uniform temperature above 4 deg C. The cold vertical wall is maintained at a constant uniform tem- perature equal to that of the initial temperature of the water
