Original abstract

The presented paper provides an introduction into the research of the fluid dynamics of a flat-panel photobioreactor. The scope of the paper deals with the setup of the baseline two-phase hydrodynamic model. The photobioreactor is modelled using the computational fluid dynamics software with the eulerian multiphase model. The assessment of the photobioreactor includes a comparison of three drag models: Grace, Tomiyama, and Ishii-Zuber. All three models are expected to be suitable for bubbles of various sizes and shapes. However, the results show that there are some differences in predictions of the gas hold-up and velocities.
