| Research Abstract |
The purpose of this study is the integration of research result accumulated until now in this study organization and information service to the researcher with small calculation experience. T results obtained are as given below ;
In the preparation of the general-purpose code, SIMPLE, SIMPLER, SIMPLEC was compared from the SIMPLE system solution method for the purpose of the selection of the solution method with the high generality, and it was shown that SIMPLEC was excellent in addition to calculation time and calculation stability.
For the purpose of the analysis accuracy improvement, new convection term difference scheme "REDS method" was developed, and the first windward difference was compared with QUICK. As the result, the usefulness in room airflow field handled in the architecture field was confirmed.
Arrangement and selection of turbulence models, mesh systems, solution method and so on were carried out, and calculation setting entry system considering the convenience in the architecture field was constructed general-purpose code. In addition, analytical result display system was constructed in order to grasp the analysis process clearly.
For the purpose of practicability examination of the general-purpose code, it made model experiment on nozzle blowing airflow and natural convection field. Calculation result and model experiment result by the general-purpose code agreed approximately, and the practicability of this code was shown.
By wearing the room air flow analysis code of the general purpose developed in this study in the wide environmental engineering field, construction of the more comfortable residential environment and more detiled elucidation of phenomena seem to become possible.
