N2 - a novel intelligent trace irrigation system based on pneumatic microfluidic chip for applications of expensive flower cultivation and seed cultivation is presented in this paper. The working principle and structural design of intelligent trace irrigation system are introduced. On-chip membrane microvalves on the pneumatic microfluidic chip are used as the water-saving device. The physical model of PDMS valve-film, on-chip membrane microvalve and intelligent trace irrigation system are given. The deformation of the flexible PDMS valve-film with different dimensions is analyzed by using ANSYS analytical software to get different valve-openings of the valve port. The numerical simulation of flow field under several valve-openings of the single on-chip membrane microvalve, and the manifold with different sets of the pneumatic microfluidic chip is carried out by using FLUENT software with UDF Function. The predicted characteristics of velocity, pressure, and flow rate of the on-chip membrane microvalve outlet under the conditions of different valve-openings of the intelligence trace irrigation system are given. According to the simulated results in this work, the on-chip membrane microvalve in parallel has both wide water-control range and fine regulation of flow rate. The simulation results confirm it is sufficient for the intended application.
