Water Temperature Homogenization for Towing Tests in Ship Model Basin and Evaluation

Abstract

　　　Homogenization of water temperature is important for quality control of a towing tank. Measurements of the vertical distribution of water temperature in a towing tank and its evaluation of homogenization by water circulation are carried out. The circulation affects the measurement of the towing tank using ship model, thus the velocity of water is commonly measured.
　　　From the measurements and discussions, it is found that 1) recognition of the characteristics of the towing tank and the equipment are important and 2) circulation of water is important because water temperature near the surface is strongly affected by room temperature.
