The Mathematical Model

In this paper, the mathematical model of a horizontal-tube falling film evaporator that used in air condition and refrigeration system was founded. The evaporative tubes of the evaporator were cold and staggered arrangement. The numerical simulation of the intervascular flow of the oil-bearing refrigerant R134a was carried out, under the conditions of varies flow mode and varies structures of distributed equipment. Under the standard condition of air conditioning, the study of the intervascular two-phase flow characters of the horizontal-tube falling film evaporator were analyzed in the last. The research achievements can provide theoretical laws for relief the effects of the intervascular vapor shear stress on the quality of the liquid film formed outside the evaporative tubes. And the conclusions have practical and guide means for the horizontal-tube falling film evaporator design and evaporative tubes arrangement optimization.

Flow Models

The predictive power of a two-phase flow design method, consisting of one-dimensional flow models depending both on flow regime and pipe inclination, has been investigated by comparing predicted pressure losses and liquid hold-ups with pipeline data collected under actual conditions. For this purpose, Shell’s database of controlled field tests in large-size gas pipelines was extended with data obtained in an 8-in. high-pressure two-phase flow test facility with gas and condensate as flowing media. It was concluded that the predictive power was reasonable for wide ranges of flow conditions, but that liquid entrainment is to be incorporated in models to remove conservatism from liquid hold-up predictions.
