摘要
A numerical technique for evaluating the performance of a closed wet cooling tower for chilled ceiling systems is presented. The technique is based on computational flow dynamics (CFD) for the two-phase flow of gas and water droplets. The eulerian approach is used for the gas phase flow and the lagrangian approach for the water droplet phase flow, with two-way coupling between two phases. Numerical simulation indicates that CFD can be used to predict the performance of a closed wet cooling tower, given the appropriate rate of heat generation from the heat exchanger. The technique is suitable for optimization of the design and operation of the cooling tower for chilled ceilings. (C) 1999 Elsevier Science Ltd. All rights reserved.
