This research was undertaken to examine a problem with respect to heat transfer and fluid dynamics, and this problem was simulated by CFD (Computational Fluid Dynamics). A tank of water with high initial temperature was exposed to an atmosphere with lower temperature than the water, which produced heat transfer at the air-water interface. The air had various magnitudes of velocity for different cases, which also generated wind shear near the interface. These two factors interacted and eventually got balanced for both thermodynamics and kinematics. The cooling plumes were observed in the initial stage when heat transfer was large due to the large difference of temperature between air and water. Also, a “fissure” separated the circulation within the tank at the final stage when the system had been balanced, and stagnation points were detected in this “fissure” on the water surface.
