Simulation For Ablation Of Axial Symmetry Based On Aerothermochemistry

ABSTRACT:The main program and the pre and post processing system frame of calculation software in the axial symmetry ablation are designed out based on both the aerothermochemistry theory and the computer languages. The axisymmetric ablation is usually caused by the high temperature, high pressure and oxidation airflow. On the base of the model for axisymmetric aerothermochemistry ablation under extreme environment, the flow field and ablation in the nozzle are simulated by using FORTRAN. From the above, the pre and post processing of the software are written through the mixed-program method combining with all the characters of MATLAB and VC++.This research introduces the basic theory of the core algorithm and programming process, some details of several mixed programming methods and corresponding examples solved by MATLAB and VC++platform. During the designing process of this software, we use the Microsoft foundation classes programming method and dynamic link library (DLL) in MATLAB. The library function and script, which generated by MATLAB, are called by VC++in order to create the axial symmetry ablation software. As a result indicated, this software can simulate the axisymmetric ablation. The advantage of this software is that it can be running under the WINDOWS system without building environment and it is easy to use the pre and post processing.
