خلاصه مقاله:
In the present work, formation of ice on a subcooled cylinder is experimentally investigated and mathematically modeled using heat transfer with phase change theories. A CFD model using COMSOL code was developed and validated with experim ental results. Our model simplifies equations and corresponding solutions for a moving boundary phase change problem using two simple yet accurate assumptions and successfully alter a moving boundary phase change problem to a simple single phase transient heat transfer problem. This modelendeavored to describe the freezing process for each study. The effect of many operating conditions like subcooling temperature on freezing rate and maximum ice width is simulated.
