Laminar-flow heat transfer and ice formation phenomena in a horizontal tube with freezing have been examined experimentally. The effect of flow acceleration accompanied by ice growth on local ice thickness was studied, and it was found that the ice thickness can be correlated in terms of a flow acceleration parameter. The effect of natural convection in a horizontal tube with internal freezing on the heat transfer is also investigated. It is shown that the average Nusselt number in a horizontal tube with internal freezing is correlated with a modified form of Oliver's empirical formula for a horizontal tube without ice.
