Abstract

The process of freeze-coating of a superheated liquid on an axially moving continuous object is investigated numerically with an exact treatment of the wall condition, i.e., allowing the local wall temperature to vary from point to point within the wall region. Also treated is heat convection from the warm liquid to the freeze coat by solving the velocity and thermal boundary layer equations for the liquid flow field adjacent to the moving object. Finite difference analysis using a fully implicit scheme is performed to determine the shape of the freeze coat, the maximum freeze-coat thickness, Δmax, and the corresponding axial location, ξmax. Criteria for selection of the optimum freeze-coating operation conditions are established utilizing the computed values of Δmax and ξmax.
