Study of a Nutrient Solution Flows in a Saturated Rockwool Slab Using the Model of Sources and Sinks

An analytical study of saline solution flows in a saturated rockwool slab, which represents a growing substrate, was developed to account for actual flow visualizations with dies and predict the solution concentration at any point of the growing substrate. Darcy flows corresponding to an injection point and to a drainage point were analytically treated by a linear superposition of periodic sources and sinks. This model was validated by the experimental results. The model of sources and sinks is simple and it gives an idea on the evolution of the nutrient solution inside the substrate.
