Research Of Heat Exchanger Simulation System Based On Virtual Reality Technique

The rapid development of computer technology makes the VR technique penetrate into every walk of life. Traditional simulation method can only provide the digital and simple figure expression way, while VR provides the observer be personally immersion feel, realizes the dynamic interaction between human and virtual world, and becomes the research hotspot and trend in simulation field.This paper uses the plate heat exchanger unit as research object, brings forward and studies the structure blue print of VR used in the heating system simulation. Based on dynamic analysis, we build its dynamic mathematics model, analyze the performance of mathematical model, and find the optimistic parameter Ropt .Then we emphases on application of the plate heat exchanger unit running dynamic simulation using virtual simulation technology. We use VRML2.0 build the 3D model of the unit, hardware equipments around and virtual scene of heat power station spot, then with Java and JavaScript, realize the dynamic interaction between dynamic data and 3D models, to obtain the dynamic 3D simulation. We probe into and build a 3D monitor and control system. Furthermore, we combine MCGS, embed the mathematical model, and finish the software design of the plate heat exchanger unit's dynamic simulation and real-time monitor and control system.Simulation result shows that the mathematical model expresses the mechanism of unit preferably. Applying the virtual simulation to the plate heat exchanger unit dynamic simulation is completely feasible and of good effects and has certain scientific and practical value as well. The 3D monitor and control system can realize the full functions of real-time monitor and control system, and it is a successful attempt, which will establish a certain base for building a more consummate and more mightiness system in the future.
