湧昇循環装置によって誘起される湖沼内流れの数値シミュレーション

The purpose of this research is solving the flow in a lake which caused by a fan who rotates at the low speed set on the water surface for the purpose of water quality purification of a lake. Although it is shown clearly by various experiments that the water quality in a lake improved by operation of this kind of equipment, the mechanism of the flow was not fully understood. In this research simulation of the flow which was caused by this equipment was carried out numerically, and the aspect of the flow corresponding to various conditions or the form of a lake was investigated.
