TEMPERATURE-TRANSFORMING MODEL FOR BINARY SOLID-LIQUID PHASE-CHANGE PROBLEMS PART II: NUMERICAL SIMULATION

Abstract

The model and numerical scheme developed in Part I were first verified with upward freezing experiments of an NH₄Cl-H₂O solution on a cold isothermal surface. Then, two-dimensional convection problems with different buoyancy terms in binary solid-liquid phase-change systems were studied. Finally, the model was used to simulate the solidification of an aqueous ammonium chloride solution in a rectangular cavity. The comparison of the results obtained from the present studies with the experimental and numerical results from the literature revealed a good agreement.
