Space station in the crystal growth experiment , the distribution of the temperature field in the crystal furnace has a direct impact on the crystal growth related to the quality of crystal growth . In order to achieve the distribution of the three - dimensional temperature field of materials science experiment process RMON crystal furnace , so that during the experiment teleoperation decision-making reference for real-time correction of experimental parameters , a crystal furnace three-dimensional temperature field modeling simulation and visualization . In this paper, the crystal furnace to its structural features and heating principle crystal furnace model simplification and the use of heat transfer theory , establish the mathematical model of crystal furnace . For solving the more complex features of the model , using the numerical solution of mesh bars crystal furnace , heat balance method to establish the energy conservation equation for each micro unit , forming an iterative equations . Then , the boundary conditions - the radiation heat transfer conditions as a single value of the model , using the iterative method of solving the equations iterative solution . Finally , the use of point-by-point insertion method , numerical solving various discrete points connected into a triangular network topology , and on this basis , the contours , to the isosurface achieve crystal furnace temperature field 3D visualization . The key technology of crystal furnace mathematical modeling , numerical solution , Delaunay triangulation , contour and isosurface rendering practice and tests to demonstrate the feasibility and effectiveness of the method .
