Water state of plants has an important effect on their growth. In this paper, water state of plant leaves were simulated using Fluent, a CFD simulation software, and principles of physiological structure of plant leaf and the water transportation were analyzed through combination of plant physiology and fluid dynamics. Firstly, a simulation model of plant leaves was established in Gambit, a preprocessor software for Fluent; after that, the model was simulated in Fluent; then the results were exported to Tecplot, a post-processing software; finally, three-dimensional data graphics of the distribution of velocity, temperature and pressure were obtained, and analysis on the simulation results were made. The result of this paper is helpful for the further study of plant leaf physiology and future water-saving irrigation.

China’s higher education has been going through a period of rapid expansion in undergraduate population,and this means a much heavier demand on teaching resources such as laboratories, experiments, teaching staff,etc., which cannot possibly be made available all of a sudden.To deal with this situation, we found virtual reality (VR) technology very helpful. Virtual reality (VR) has found many applications in education; and the resources of virtual education such as virtual campus, virtual laboratory etc. are used more and more widely, especially in the field of higher education. But so far virtual campus was mainly regarded as a means of image exhibition, and virtual laboratories were no more than 2D display of experimental processes and equipments. To make better use of these resources, this paper puts forward the concept of networked virtual experiment systems based on virtual campus by combining the virtual laboratory and virtual campus with the technique of LAN (Local area network), and establishes its theoretical model. Finally, a networked virtual experiment system based on virtual campus is developed using VRML and 3DSMAX. Networked virtual experiment system based on virtual campus has a promising future for various applications in higher education.
