Fluid to fluid convection
WebApr 13, 2024 · In general, natural convection is the mechanism behind hot air rising and cold air falling and similar phenomena.) Forced convection, which is fluid flow caused by non-natural mechanisms such as by a pump. In your case we have natural convection: The water particles near the ice surface deliver heat to the ice and in turn cool down.
