氷層の温度・濃度複合融解 : 第1報,垂直氷板と液層の初期温度が同じ場合

抄録

Experimental and numerical investigations are carried out on the melting of a vertical ice plate into a calcium chloride aqueous solution inside an insulated rectangular cavity. The ice plate melts spontaneously even when there is no temperature difference between the ice and the liquid. It is found that the temperature at the melting front decreases monotonically from the initial temperature due to the mass-diffusion controlled melting of the ice. The melting rate is significantly affected by a combination of natural convection with the temperature and concentration of the liquid. It is shown that the numerical model predicts well the melting rate and temperature drop at the melting front.
