Investigation of the Adhesion of Enteromorpha Clathrata and the Consequent Impact on Cavitation and Dynamic Response of Hydrofoil/Lifting Surfaces of Underwater Vehicles

9312890温伯利以前由国家科学基金会资助的研究导致了关于污垢生物的附着特性以及由此对平板流体动力阻力的影响的重要信息。本研究是对这项工作的延伸，其目的是：首先，继续研究壶形蛔虫的附着特性，从而表征防污涂料对藻类生长和附着的影响；其次，调查快速生长的裙带藻培养物对涂有三丁基锡基涂料的提升表面的影响。本课程将研究与光照强度和质量、酸碱度、盐度、温度、营养水平和养殖年龄等几种环境条件有关的藻类在抬升表面的生长模式。计算结果将被用来对水下升力面和支撑结构对流场空化的影响、水动力响应和控制特性进行数学建模。

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.
