Tests are conducted using models in which various fluid conditions are reproduced in a water tank (called a test tank) to investigate the hydrodynamic performance of ships and marine structures. The first such tests were conducted in the late 19th century by the British scientist William Froude (1810-1879) to study the performance of ships. Since there is a limit to what can be explained by the theory of fluid mechanics, experimental investigations and research using water tank tests are essential for the development and design of ships and marine structures, the study of the motion of fluids themselves, as well as for identifying problems in theory and building new theories.

船や海洋構造物の流体力学的な性能を調査するため,各種の流体の状態を水槽(試験水槽という)内に再現し,模型を使って行う試験。19世紀後半,イギリスのフルードWilliam Froude(1810‐79)が船の性能を研究するために行ったのが最初である。流体力学の理論で説明できることには限度があるので,水槽試験による実験的調査や研究は,船や海洋構造物の開発,設計の際の基礎データの収集,流体の運動そのものの研究,あるいは理論の問題点の把握や新しい理論の構築などのためにはかかせないものとなっている。
