Fluid filtration in microcirculator mesh of plant leaf: development and investigation of the model with lumped parameters

Applied hydromechanics, Vol. 7 (79) ¹ 2, (2005) p.33-43
Stationary filtration of a viscous incompressible liquid in the system consisting of the channel with impermeable walls, surrounded by the non-uniform anisotropic porous medium is investigated. Movement of the liquid through the channel and the medium is determined by gradients of hydrostatic and osmotic pressures. The problem is related to the sap flow in plant leaves. The considered system is a generalization of Krogs' cylinder for a plant tissue. By averaging the system of the equations the ratio for quasi-one-dimensional model are received. Various modes of the dynamic system are investigated at different parameters of the model. Expressions for the averaged pressures, volumetric rates and concentrations of osmotically active components are obtained.
