Numerical Simulation of Water Transport through Vessel Perforation Plates

Abstract:

The structure of perforation plate had a substantial effect on the water conductivity of plant vessels. As the microscopic structure of vessel and perforation plate is highly complex, it is very difficult to numerically solve the flow equations. The effects of perforation plate structure on water flow in plant xylem vessels were studied using CFD (computational fluid dynamics) approach, the calculation results were used to estimate the effects of the perforation plate on conductance. Results showed that simple plate provided less resistance than scalariform plate. The resistance to flow through the perforation plate increased as the plate angle increased (giving same number of pores). Increasing the pore size would reduce the resistance along the modeled vessel. The results also showed that gravity had hardly effect on flow characteristics in micro vessels of plant and nearly can be neglected.
