摘要

A mathematical model for the optimization of ice making in a laminar falling film is presented. The model is first val-idated, and a series of numerical experiments are conducted to assess the effects of the mass flow rate, the inlet water tern-perature and the length and temperature of the cold plate on ice accumulation. The results are then correlated in a simple algebraic expression for the frequency of the intermittent freezing and removal cycle that maximizes the production of ice. Applying this calculation procedure to a commercial system, it is shown that the same amount of ice can be produced in a time interval more than six times shorter.
