What is Numerical Modeling of a Falling Bioconvection Plume in a Porous Medium about?

This paper considers a bioconvection plume in a fluid saturated porous medium. Bioconvection plumes may arise as a result of an unstable density stratification caused by up-swimming microorganisms. This unstable density stratification occurs when the microorganisms, heavier than water, accumulate in the upper regions of the fluid. The plume transports cells and oxygen from the upper fluid region to the lower fluid regions. This paper finds a numerical solution for the steady-state plume in a porous medium by utilizing an implicit finite difference method. The effects of varying pertinent parameters are investigated. A similarity solution of the plume is also obtained for comparison purposes.
