SGER: The Effect of Small-Scale Fluid Motion on Growth and Aggregate Formation of Freshwater Algae

本研究的目的是研究绿藻魔羯座硒藻和蓝绿藻利奥聚藻在一个明确的流动系统中的生长动态。本研究将验证一个假设，即这些藻类的生长和聚集形成不仅取决于最佳水温、光照条件和营养物质，还取决于水动力混合条件。为了验证这一假设，将在层流、湍流和湍流-间歇流体条件下对这些藻类进行实验研究，以表征其生长、聚集形成和形态测量作为固有流体流动参数的函数。流体流动条件将同时使用旋转圆柱体装置和振荡网格装置来产生。本研究可为改进淡水系统中藻华预测模型的开发提供数据。

0127887HondzoThe objective of this research is to investigate the growth dynamics of the green alga Selenastrum capricornutum and the blue-green alga Synechococcus leopoliensis in a well-defined flow system. This research will test the hypothesis that the growth and aggregate formation of these algae depends not only on optimal water temperature, light regime, and nutrients, but also on hydrodynamic mixing conditions. To test this hypothesis, experimental studies of these algae will be conducted under laminar, turbulent, and turbulent-intermittent fluid flow conditions in order to characterize the growth, aggregate formation and morphometry as functions of intrinsic fluid flow parameters. Fluid flow conditions will be generated using both a rotating cylinder apparatus and an oscillating grid apparatus. This research could provide data for improved model development for the prediction of alga blooms in freshwater systems.
