Abstract

The primary objective of this article is to explore how rotation influences the initiation of phototactic bioconvection. This investigation is conducted through the application of linear stability theory to a suspension composed of forward-scattering phototactic algae. The suspension is uniformly exposed to oblique collimated flux. The bioconvection phenomenon is characterized by an unstable disturbance mode that undergoes a transition from a stationary state to an oscillatory state as the Taylor number varies while keeping other parameters constant. Additionally, it is noteworthy that rotation of the system has a substantial stabilizing effect on the suspension.
