论文摘要
我们考虑了一个耦合的物理生物学模型，描述了在赛道池塘培养过程中微藻的生长，这考虑了流体动力学。我们的方法结合了一个生物学模型（基于HAN模型）和浅水动力学方程，该方程将流体建模到赛道池塘中。我们提出了一个针对地形的优化程序，以用桨轮在一圈或多圈上最大化生物质产生。与对微藻场的普遍信念相反，结果表明，平坦的地形在周期性的方向上是最佳的。在其他框架中，可以获得非平凡的地形。我们提出其中一些，例如，当模型中包含混合设备时。
We consider a coupled physical-biological model describing growth of microalgae in a raceway pond cultivation process, accounting for hydrodynamics. Our approach combines a biological model (based on the Han model) and shallow water dynamics equations that model the fluid into the raceway pond. We present an optimization procedure dealing with the topography to maximize the biomass production over one lap or multiple laps with a paddle wheel. On the contrary to a widespread belief in the microalgae field, the results show that a flat topography is optimal in a periodic regime. In other frameworks, non-trivial topographies can be obtained. We present some of them, e.g., when a mixing device is included in the model.
