Abstract

Hydraulic experiments were examined to investigate the characteristics of thermal convection based on inhomogeneous water surface cooling in a closed water body where aquatic plants grew thickly. We demonstrated the process of the generation and development of thermal convection from the results of water temperature measurement experiments. This explained the development process of convection was divided into three stages. Aquatic plants disturb the thermal transportation at the water surface, and the aspect ratio of the convection cell changes by the magnitude of the density difference near without the plants. Moreover, the development process of the thermal convection when the shield existed in the water surface was simulated by numerical experiment. As the result, it was clarified that the balance of the transportation equation of the turbulent energy.
