ABSTRACT:
The dynamic testing of materials in moving solutions, such as anti-fouling paint in seawater, is conducted in a cylindrical tank. A stirrer having a drive shaft and one or more paddles or blades is driven by a variable speed motor to rotate and to impart rotational velocity to a liquid, which passes over the test materials which are attached to the periphery of the tank. The flow conditions over the surface can be well characterized. The surface of the test materials may be instrumented to measure physical, chemical and hydrodynamic conditions. The energy required for testing is reduced over prior art techniques.
