Physical Model Test on Cooling Water with PIV and Thermal Infrared Imager System

The impact on flow field and temperature field of water area near discharge outlet usually is forecasted by physical model for studying mixing regularity and diffusing regularity of cooling water which is discharged by heat power plant and nuclear power plant. But people gained little quantitative results because of testing method's limitation. Based on the previous studies, the research in this paper is done on physical model test of cooling water with PIV (Particle Image Velocimetry) and thermal infrared imager system. Based on similarity theory, four variability conditions such as normality, variability two, variability three and variability four are defined. The main work in the paper is summarized as follows: (1) Planar flow field in different variability conditions is measured by PIV; and the data of flow field is compared and analyzed in this article. (2) Surface temperature field is measured by thermal infrared imager system, and the data of surface temperature is compared and analyzed in this article.
