The problem of freezing of a liquid in laminar and turbulent flow inside a circular tube whose wall is cooled below the freezing temperature of the liquid is solved by numerical method, for constant flow rate and varying flow rate due to increased friction by reduced flow region.
The radius of the solid-liquid interface and the local heat flux at the interface are determined as a function of time and position along the tube for several different values of the Prandtl number and other freezing parameters.
