（实验步骤） The experiments were performed using the following procedure. Ice particle were mixed with water in the ice water slurry tank. After controlled IPF and velocity of ice water slurry, is was passed through the test section and heated by hot water. The amount of melting heat transferred from hot water to ice water slurry was calculated with the difference between the inlet and outlet temperature of hot water. In addition, the behavior of the ice particles passed through the test section was recorded by a video camera for flow visualization.

例 Results （介绍研究结果）Table 1 shows that the measured drop
△Texh caused in the temperature of exhaust gases between the inlet to the heat exchanger and the exit from it is considerably more than what was predicted by modeling studies. （叙述最重要的结果）Thus, referring to Table 1, it is observed that the △Texh values measured on the actual setup are considerably above the predicted values. This occurrence is especially striking at the tower inlet temperature. （推论）These observations signal that the modeling was on the conservative side.

（实验装置）The schematic diagram of experimental apparatus is shown in Fig.1. The apparatus consisted of a test section, an ice water slurry tank, a hot water circulating loop, and associated measuring instruments. The test section was a horizontal double tube heat exchanger of 2,000mm in length with an entrance section of 800mm in length. Ice water slurry flowed in an inside tube of the heat exchanger and hot water circulated in an annular gap between the inside and outside tubes. In this study, two kinds of heat exchanger were used. One was … and the other was ….
