Study of free convection in binary systems with phase change
Jerzy Banaszek , Piotr i in Furmański
AbstractThe thermal convection of water and aqueous solution of sodium chloride is investigated experimentally and numerically in a cubic cavity, with two opposite vertical walls kept at prescribed temperature. The analysis is carried out for the pure convection of water in the vicinity of the freezing region (cold wall temperature T-c = 0 degrees C), and for convection of water and its solute accompanied by freezing (T-c less than or equal to -10 degrees C). The opposite hot wall temperature is fixed at +10 degrees C. The time history of the velocity and temperature fields are measured using liquid crystals seeding. It was observed that the thermal boundary conditions of non-isothermal side walls have a triggering effect on the now configuration. Investigated thermosolutal convection demonstrated transition from a double-circulation flow pattern observed for the pure water to the single, double roll circulation at the upper part of the cavity with a wide stagnant layer at the bottom.
