摘要：

The isothermal flow losses through an array of A-frame finned tube heat exchangers are determined experimentally. Correlations that describe these losses are derived from scale-model tests conducted on different V-bundle configurations, each simulating a section of a typical A-frame array. The experimental data are then compared with test data obtained from a full-scale heat exchanger installation. It is found that the downstream flow losses behind a V-bundle section are significantly influenced by the semiapex angle, the process stream duct diameter, and the distance between the A-frames.
