Phototactic bioconvection under oblique collimated irradiation in a forward scattering suspension

A. Rathi, M. K. Panda, S. K. Rajput

Phototaxis, the process by which living organisms navigate toward optimal light conditions, is essential for motile photosynthetic microorganisms. Positive(negative) phototaxis den…
