Research On Data Visualization And Fluid Simulation For PbBi Experimental Loop Simulation System

Energy has become one of the most important worldwide concerning issues, and energy is getting more and more attention for it is efficient and clean. Institute of Nuclear Energy Safety Technology, Chinese Academy of Sciences, FDS Team, independently established PbBi experimental loop KYLIN-II, which is an important experimental platform for advanced nuclear reactor research. By taking use of virtual reality, data visualization and fluid simulation technology, PbBi experimental loop simulation system is developed to assist researchers to design experiments, observe the experimentation process, and analyze experiment data for carrying out related research more effectively and efficiently. The dissertation’s main contents are as the following:(1) Overall design and implementation of the Simulation system:PbBi experimental loop simulation system’overall design is given according to PbBi experimental loop’s structural characteristics and user requirement, which consists of scenes models processing, the simulation data acquisition, data visualization module and multi-screen display module. Furthermore, detailed design and implementation of different functional modules are given in the dissertation.(2) Intuitive visualization of physical data:There are different experiment data(i.e. fluid temperature, fluid pressure and fluid velocity) in PbBi experimental loop. Visualization can be used to intuitively and effectively demonstrate these physical data, so that the researchers can better understand the data and carry out the related experiments. Temperature data is one of the core experiment datas in PbBi experimental loop. The dissertation realizes integrated visualization of geometry model and the temperature field by coloring the geometric model through 2D texture, so that three-dimensional temperature field can be demonstrated efficiently.(3) Particle system based adaptive fluid simulation:Liquid PbBi fluid is an important part of PbBi experimental loop. The researchers can better understand the related experiments by observing Liquid PbBi fluid’s motion. As Liquid PbBi flows in Loop, the dissertation presented particle system based adaptive fluid simulation method, which automatically generates fluid model based collision detection between particles and loop. The presented method can avoid complex modeling of fluid boundary.
