Ship model basin
A ship model basin is a physical basin or tank used to carry out hydrodynamic tests with ship models, for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization (often a company) that owns and operates such a facility.
A ship model basin company is an engineering firm that acts as a contractor to the relevant shipyards, and provides hydrodynamic model tests and numerical calculations to support the design and development of ships and offshore structures.
==History==
The eminent English engineer, William Froude published a series of influential papers on ship designs for maximising stability in the 1860s. The Institution of Naval Architects eventually commissioned him to identify the most efficient hull shape. He validated his theoretical models with extensive empirical testing, using scale models for the different hull dimensions. He established a formula (now known as the Froude number) by which the results of small-scale tests could be used to predict the behaviour of full-sized hulls. He built a sequence of 3, 6 and (shown in the picture) 12 foot scale models and used them in towing trials to establish resistance and scaling laws. His experiments were later vindicated in full-scale trials conducted by the Admiralty and as a result the first Ship model basin was built, at public expense, at his home in Torquay. Here he was able to combine mathematical expertise with practical experimentation to such good effect that his methods are still followed today.
Inspired by Froude's successful work, shipbuilding company William Denny and Brothers completed the world's first commercial example of a ship model basin in 1883. The facility was used to test models of a variety of vessels and explored various propulsion methods, including propellers, paddles and vane wheels. Experiments were carried out on models of the Denny-Brown stabilisers and the Denny hovercraft to gauge their feasibility. Tank staff also carried out research and experiments for other companies: Belfast-based Harland & Wolff decided to fit a bulbous bow on the liner ''Canberra'' after successful model tests in the Denny Tank.〔 (【引用サイトリンク】title=The Scientific and Management Revolution in Shipbuilding on the “Two Clydes,” 1880-1900 )〕
