Abstract

The effect of ultrasonic irradiation on nucleation phenomena in the heat storage material CH₃COONa·3H₂O was investigated by measuring the nucleation probability and induction time. The experimental results show that the concentration of CH₃COONa should be operated in the optimum range for CH₃COONa·3H₂O-selective crystallization. Furthermore, the nucleation probability increased and the induction time decreased with increasing energy input. Consequently, the optimum conditions of ultrasonic irradiation of CH₃COONa·3H₂O are 53wt-% CH₃COONa, 3.0W of energy input, and ΔT = 10-68K.
