This paper analyzes heat transfer and loss of pressure in the flow of a viscous melt in a capillary, the walls of which have been subcooled to a temperature below that at which the melt solidifies. This situation may arise in various shaping processes used in polymer and chemical engineering, generally in all cases in which a melt is to be transported in a tube which is inadequately heated. Inadequate heating of this type frequently gives rise to a characteristic process referred to as “freezing of the capillary”.
