The project is modeling the effect of fluid turbulence on the growth rate of algae. The current project will develop a stochastic Lagrangian approach that can be coupled to Reynolds-averaged Navier-Stokes models of turbulent flow to provide efficient, accurate prediction of algae growth rate enhancement by turbulent mixing. We are performing a proof-of-concept of this approach by comparison with direct numerical simulation results for homogeneous turbulence. In future research we plan to extend this model to anisotropic turbulent flow conditions as generally prevail near a wall boundary or a free surface, which is where the majority of algae growth occurs. Commercially produced algae has a wide variety of uses, including usage as animal feed and nutritional supplements for humans. Alage can also be used in the production of bio deisel. Also, aglae growth systems are currently being investigated by the USDA as a method for on-site remediation of agricultural wastewater.
