9312890 Wimberly Previous research supported by the National Science Foundation led to important information on the adhesion characteristics of fouling organisms and the resulting effect on the hydrodynamic drag of flat plates. This research is an extension of this work with the intention of first, continuing the investigation of the adhesion characteristics of Enteromorpha clathrata and thus characterizing the effects of antifouling paints on algal growth and adhesion, and secondly, investigating the effects of rapidly growing Enteromorpha clathrata cultures to lifting surfaces coated with tributyltin-based paints. The algal growth patterns on lifting surfaces in relation to several environmental conditions such as light intensity and quality, pH, salinity, temperature, nutrient levels and culture age will be investigated. The results will then be used to mathematically model the consequent impact on flow field cavitation, the hydrodynamic response and control characteristics of underwater lifting surfaces and support structures.

9312890 Wimberly先前由美国国家科学基金会支持的研究提供了关于污垢生物的粘附特性及其对平板流体动力阻力的影响的重要信息。本研究是本工作的延伸，目的是首先继续研究笼形Enteromorpha clathrata的粘附特性，从而表征防污涂料对藻类生长和粘附的影响，其次，研究快速生长的笼形Enteromorpha clathrata培养物对涂有三丁基锡基涂料的提升表面的影响。研究了不同环境条件（如光照强度和质量、pH值、盐度、温度、营养水平和培养年龄）对提升表面藻类生长模式的影响。研究结果将用于对流场空化、水下提升面和支撑结构的水动力响应和控制特性的影响进行数学建模。
