碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 102 / Fu was developed an innovation Photobioreactor,’’ Automatically Tempe-rature Controllable and Wave-Mixed Photobioreactor System , ATCWPS’’ at 2012. The main of the function is let the microalgae can be grown under a stable temperature by the high specific heat of seawater , and use the energy of waves to achieve the mixed effect by sloshing a tank. When a tank with the horizontal baffles, the liquid sloshing caused the vortex to push more microalgae mixed, and increase the efficiency of mixed from the bottom of a sink.
The theoretical basis of this study is established at computational fluid dyn-amics software "Fluent" , that simulate tank sloshing with User Defined Function (UDF) , as well as the free surface being Volume of Fluid (VOF) method tracked and calculated . For the accuracy of numerical simulation , this study was verified by rigorous benchmark tests , that compared with the numerical analysis of biblio-graphy, and the result of experiment by equipment on hand.
According to the simulation results can be affected when the external shocks that sinks its internal fluid flow rate of the liquid mixing efficiency is not the most important factors, caused vortex separator can effectively increase the mixing efficiency microalgae. In different baffles configuration, when vortex caused by baffles can cover the entire internal tank fluid mixing efficiency can reach the highest point.
