Effects of Flow Rates and Cooling Water Temperatures to Temperature Profiles around a Cooling Pipe and Their Analyses

Abstract

The purpose of this paper is to investigate the effects of flow rates and cooling water temperatures to temperature profiles of concrete around a cooling pipe. A series of laboratory tests using specimens (60 × 60 × 50cm) with a cooling pipe was conducted. Various flow rates and cooling water temperatures were adopted in the tests. It was found from the experimental results that the effects of cooling water temperatures to the temperature histories around the pipe were stronger than those of water flow rates. FEM analysis results indicated that the simulation results showed good agreements to the experimental ones.
