Natural convection of water near 4°C in a bottom-cooled enclosure

Abstract

A study of natural convection in water-filled square enclosures whose bottom wall is cooled at 0°C, whereas the top wall is partially or entirely heated at a temperature ranging between 10°C and 30°C is performed numerically through a computational code based on the SIMPLE-C algorithm, assuming temperature-dependent physical properties, for cavity widths in the range 1 cm-10 cm, with the main aim to point out the basic heat and momentum transfer features.
